Question

Given that f(x) = x² + 5x, evaluate f(-2).

Answer 1

no but do you know 8-4x>-12

Answer 2

f(-2)=4+5*(-2)=4-10=-6
f(-2)=-6

Answer 3

f(0) = 0^2 + 5(0)
f(1) = 1^2 + 5(1)
f(dog) = dog^2 + 5(dog)
f(g(x)) = g(x)^2 + 5(g(x))

Sometimes, you DO just substitute.

Answer 4

Evaluate g(3) if g(x) = 2x + 1.

Answer 5

You do it. You MUST understand this notation. Substitute and simplify.

Answer 6

i i understood how to do it i would of done it. i wouldnt of posted it on here

Answer 7

just put the value instead of x

Answer 8

thanks man

Answer 9

Given that f(x) = x² + 5x, evaluate f(-2). So what is the value of function at x=-2
(-2)^2+5(-2)=4-10=-6

I really do not like that response. Do you see the examples above? What happened? Do you have any course materials? How was it explained?

I see. So you get to select the purpose of the forum and not the forum sponsors? Nice. Please read the Code of Conduct. If you wish to live by some other rules, you may wish to do it somewhere else. The slightest amount of social conformity can go a long way.

We can't be there on your exams. YOU must learn how to produce the proper results. This takes effort from YOU. Keep in touch.
