Question

If f(x)=-3x-1, find f(4)

Answer 1

just replace all the x's in f(x)=-3x-1 with 4

Answer 2

Thanks

Answer 3

If f(x)=-x2+x divide by x, find f(2)

Answer 4

@spandana please don't just give the answer
Please try to get the asker involved next time.
Thanks.

Answer 5

Do you know the answer?

Answer 6

you should try this one @BethMoses2008
f(2) means to replace all the x's with 2's in f(x)=-x^2+x

Answer 7

okay thanks

Answer 8

what did you get when you replaced all the x's with 2's?

Answer 9

@BethMoses2008 Since you know how to do it, can you find the answer?

Answer 10

Is 4

Answer 11

4^3+1=65

Answer 12

ok first step i asked you to do what to replace all the x's with 2's
so you have -2^2+2

what is 2^2?

Answer 13

If f(1) f(x)=4x^3+x, find f(1)

Answer 14

I think it's 65

Answer 15

I'm trying to tell you answered incorrectly to the previous one
the answer is not 4.

Answer 16

-2^2+2 is not 4

Answer 17

It's 3

Answer 18

Right

Answer 19

Typ

Answer 20

I forgot to add 2

Answer 21

Nevermind

Answer 22

If f(x)=-2, find f(5)

Answer 23

well 3 is not the right answer to evaluating -2^2+2

let's try to take it slow
you are to apply order of operations

there are no grouping symbols
so let's do the exponents
the exponent is only on the 2
if were to be on the -2 it would look like (-2)^2 but we have -2^2


so first exponents
what is 2^2?

Answer 24

If f(x)=-2, find f(5)

Answer 25

if you aren't willing to answer my questions, then i cannot help you. sorry.
