HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5

Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

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

To evaluate the value of f(-2), substitute -2 for x. Thus:

$f(-2)=3(-2)^2+2(-2)-5$

Square first:

$f(-2)=3(4)+2(-2)-5$

Multiply:

$f(-2)=12-4-5$

Now, subtract:

$f(-2)=8-5=3$

So:

$f(-2)=3$

And we're done!
