All you need to do is repalce each x with the givenvalue

$f (x) = 3 x^{2} + 4 x + 2$

$f (0) = 0^{2} + 4 (0) + 2 = 2$

$f (3) = 3 {(3)}^{2} + 4 (3) + 2$

$= 27 + 12 + 2 = 41$

$f (- 5) = 3 {(- 5)}^{2} + 4 (- 5) + 2$

$= 75 - 20 + 2 = 57$

$f (b) = 3 {(b)}^{2} + 4 (b) + 2$

$= 3 b^{2} + 4 b + 2$

$f (5 a) = 3 {(5 a)}^{2} + 4 (5 a) + 2$

$= 3 (25 a^{2}) + 20 a + 2$

$= 75 a^{2} + 20 a + 2$

Let R be the relation on the set {0, 1, 2, 3} containing the ordered pairs (0, 1),(1, 1),(1, 2),(2, 0),(2, 2),(3, 0). Find reflexive, symmetric and transitive closure of R.
A baseball team plays in a stadium that holds 70,000 spectators. With the ticket price at $11, the average attendance has been 29,000. When the price dropped to $10, the average attendance rose to 35,000. Assuming the demand function, p(x) $p (x)$ , is linear, find p(x) $p (x)$ , where x $x$ is the number of the spectators. Write p(x) $p (x)$ in slope-intercept form.
To break even in a manufacturing business, income or revenue R must equal the cost of production the letter C. The cost the letter C to produce X skateboards is the letter C = 108+21X. The skateboards are sold wholesale for $25 each, so revenue the letter R is given by the letter R = 25 X. Find how many skateboards the manufacture needs to produce and sell to break even. (Hint: set the cost expression equal to the revenue expression and solve for X.)
