Question

If f(x)= -7x+22 then f(2)= and f(x+1)=

Answer 1

HI welcome to Openstudy!

f(x)--> f(2)
x=2
so just substitute 2 on the equation f(x)= -7x+22
\(f(2)=-7(2)+22\)



same thing for f(x+1)
it will be:
\(f(x+1)=-7(x+1)+22\)

simplify them and tell me what you get.

Answer 2

Okay f(2) =8 and
f(x+1)= -7x-21
or 3

Answer 3

And thank you for your assistance

Answer 4

\(f(2)=−7(2)+22\\=-14+22=8\)
this seems right:)
next one..

\(f(x+1)= -7(x+1)-22\\=-7x-7-22\\=?\)

Answer 5

no problem:)

Answer 6

Ohhh I mistakenly placed one where it suppose to be 7--- -7x-29

Answer 7

Is that right ?

Answer 8

yes :)
sorry i was already off last night
