Question

Let f(x) = −4x + 7 and g(x) = 10x − 6. Find f(g(x)).

Answer 1

ok hold on

Answer 2

so graph this and you will get your first awser y=−4x+7

Answer 3

okay

Answer 4

HI!!

Answer 5

it does not say to graph, does it?

Answer 6

and then hears how you do the 2nd part of your problem Let's solve for g.
gx=10x−6
Step 1: Divide both sides by x.
gxx=10x−6x
g=10x−6x
Answer:
g=10x−6x

Answer 7

lol oooooooh nooooooooo!

Answer 8

y what am i doing wrong

Answer 9

solve for \(g\)??!! darling, \(g\) is not a variable
\(g(x)\) is a function
it is \[g(x)=10x-6\]

Answer 10

im lost

Answer 11

\[f(x)=-4x+7\\
g(x)=10x-6\] so
\[f(g(x))=f(10x-6)\] is the first step

Answer 12

then since \[\huge f(\clubsuit)=-4\clubsuit +7\] you have \[\huge f(10x-6)=-4(10x-6)+7\]

Answer 13

a little algebra will clean that up nicely

Answer 14

would i just solve it like a regular two variable equation or how do i do it with f
