Question

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

Answer 1

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

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`
