Question

5 Given the function below, find f(-4). * (2 Points) f (x) 22 + 3x-5 -10 39

Answer 1

We have the function:

`f(x)=2x^2+3x-5`

And we have to find f(4), this is the value of the function when x=4.

To do that we have to replace the x's in the equation by the value 4:

`f(4)=2(4)^2+3(4)-5=2\cdot16+12-5=32+12-5=44-5=39`

The value of f(4) is 39.
