Step 1
Given function is f(x)=x3
To write the equation of transformed function.
Solution:
Given function is f(x)=x3.
We know that when y=f(x) is stretched vertically by c units then function becomes y=cf(x).
So, when function f(x)=x3 is strectched vertically by 2.5 then function will becomes y=(2.5)x3
Step 1
Given function is f(x)=x3
To write the equation of transformed function.
Solution:
Given function is f(x)=x3.
We know that when y=f(x) is stretched vertically by c units then function becomes y=cf(x).
So, when function f(x)=x3 is strectched vertically by 2.5 then function will becomes y=(2.5)
Now, the graph of the function y=f(−x) is the graph of y=f(x) reflected in the y-axis.
So, when y=(2.5)x3 isreflected in the y−axis then function will become y=(2.5)(x)3 And if c is positive real number then graph of f(x−c) is the graph of y=f(x) shifted horizontally by c units.
So, when y=(2.5)(x)3 is shifted left by 1 unit then function will be g(x)=(2.5)(x+1)3.

To find the equation of the transformed function, we need to apply the given transformations to the parent function f(x)=x3 in the specified order. Let's go through each transformation step by step.
1. Vertical stretch by a factor of 2.5: We multiply the parent function by 2.5. The equation becomes g(x)=2.5·f(x).
2. Reflection over the y-axis: We replace x with x in the equation. The equation becomes g(x)=2.5·f(x).
3. Horizontal translation left by 1 unit: We add 1 to x in the equation. The equation becomes g(x)=2.5·f(x+1).
Therefore, the equation of the transformed function g(x) is g(x)=2.5·f(x+1)=2.5·(x+1)3.

Answer:
g(x)=2.5·f(x1)=2.5·(x1)3
Explanation:
The parent function is given as f(x)=x3. We need to apply the following transformations to obtain the equation of the transformed function, g(x), in the described order:
1. Vertical stretch by a factor of 2.5: To vertically stretch a function, we multiply the function by the stretch factor. Therefore, the first transformation can be written as g(x)=2.5·f(x).
2. Reflection over the y-axis: To reflect a function over the y-axis, we replace x with x. Hence, the equation after the reflection becomes g(x)=2.5·f(x).
3. Horizontal translation left 1 unit: To translate a function horizontally, we add or subtract a value from x. In this case, we translate left 1 unit, so we subtract 1 from x. Thus, the equation after the translation becomes g(x)=2.5·f(x1).
Combining all the transformations, the equation of the transformed function g(x) is:
g(x)=2.5·f(x1)=2.5·(x1)3

Step 1. Vertical stretch by a factor of 2.5: To vertically stretch the function, we multiply the parent function by the stretch factor. The equation becomes:
g(x)=2.5·f(x)
Substituting the parent function f(x)=x3, we get:
g(x)=2.5·x3
Step 2. Reflection over the y-axis: To reflect a function over the y-axis, we replace x with -x in the equation. The equation becomes:
g(x)=2.5·(x)3
Simplifying the exponent, we have:
g(x)=2.5·(x)3=2.5·(x·x·x)=2.5·(x3)
Step 3. Horizontal translation left 1: To translate a function horizontally, we add the translation value to x. In this case, we're translating left 1 unit, so we add 1 to x. The equation becomes:
g(x)=2.5·((x+1))3
Combining all the transformations, the final equation of the transformed function g(x) is:
g(x)=2.5·((x+1))3
This equation represents a function obtained by vertically stretching the parent function f(x)=x3 by a factor of 2.5, reflecting it over the y-axis, and horizontally translating it left 1 unit.
