Question

Use the quadratic function to predict f(x) if x equals 2. f(x) = -3x^2 + 180x - 285

Answer 1

Answer:

When x = 2, f(x) = 63.

Step-by-step explanation:

In order to find the value of f(x), you have to substitute x = 2 into the function :

$f(x) = - 3 {x}^{2} + 180x - 285$

$f(2) = - 3{(2)}^{2} + 180(2) - 285$

$f(2) = - 12 + 360 - 285$

$f(2) = 63$
