Step 1
The general form of parabula is:
y=a(xh)2+k
Given that (h, k)=(1, 0)
So, y=a(x1)2+0
y=a(x1)2
Now, the curve puos through (0, 1)
1=a(01)2
a=1
Hence, the required equation
y=1(x1)2+0
y=(x1)2
So, f(x)=(x1)2

Answer:
y=(x1)2
Explanation:
y=a(xh)2+k
where (h, k) represents the vertex of the parabola.
Given that the vertex is (1, 0) and a point on the graph is (0, 1), we can substitute these values into the equation to solve for 'a'.
Using the vertex coordinates, we have:
0=a(11)2+0
Simplifying the equation, we get:
0=a(0)+0
0=0
Since the equation simplifies to 0 = 0, this equation does not provide any information about 'a'. Therefore, we need to use the point (0, 1) to solve for 'a'.
Substituting the point coordinates into the equation, we have:
1=a(01)2+0
Simplifying further:
1=a(1)2
1=a(1)
1=a
Now that we have found the value of 'a' as 1, we can substitute it back into the vertex form equation to obtain the general form of the quadratic function:
y=1(x1)2+0
Simplifying:
y=(x1)2
Thus, the general form of the quadratic function is y=(x1)2.

Given:
y=a(xh)2+k.
Given that the vertex is (h,k)=(1,0) and a point on the graph is (x,y)=(0,1), we can substitute these values into the equation:
1=a(01)2+0.
Simplifying the equation, we have:
1=a(1)2.
Squaring 1, we get:
1=a.
Therefore, the general form of the equation for the quadratic function is:
y=1(x1)2+0.

Step 1:
To find the general form of the equation for a quadratic function using the vertex (h,k) and a point on the graph (x,y), we can start with the vertex form of the quadratic equation:
f(x)=a(xh)2+k
where (h,k) represents the vertex of the parabola. Plugging in the given vertex values (h,k)=(1,0), we have:
f(x)=a(x1)2+0
Simplifying further, we get:
f(x)=a(x1)2
Step 2:
Now, let's substitute the coordinates of the point (x,y)=(0,1) into the equation:
1=a(01)2
Simplifying the expression on the right-hand side, we have:
1=a(1)2=a
Therefore, the value of a is 1.
Substituting this value back into the equation, we get the final general form of the quadratic function:
f(x)=(x1)2
