Question

I have trouble starting these :/
f(x) = 2x + 7 and f(x) = -1

Answer 1

Plug the value of f(x), which is -1, into the function. 2(-1)+7= -2+7=5

Answer 2

I am not sure what the question is?
are they asking to find x ?

@sujuexob2st that would be if they gave f(-1) and f(x) = 2x + 7 :)

Answer 3

@Emz.Yaoi oh true, I never though of that, but I just assumed that it would be the case of f(-1)

Answer 4

its coming straight off my homeqwork ...
but i think 5 is right

Answer 5

I was guessing f(x) = f(x)
so 2x + 7 = -1 solve for x

Answer 6

if which case it would be -4, not 5

Answer 7

Well its multipal choice and both awnsers are on there ..

Answer 8

f(2) if f(x) = (x + 1)2 what about this one ?

Answer 9

that would would be f(2) means to plug in 2 for x :)
