Answer 4

for #1.. just substitute 1 to the function f ..

Answer 5

@itsmeeQUENNIE thank you <3

Answer 6

\(g(f(x))\) means to put f(x) into g(x). In other words, take the expression for g(x) and put it into the argument for f(x), then simplify as follows:

\(f(x) = 6x + 2\)

\(g(x) = \dfrac{2x+4}{5}\)

Putting f(x) into g(x):

\(g(f(x)) = \dfrac{2(6x+2) + 4}{5}\)

\(= \dfrac{12x+4 + 4}{5}\)
\(= \dfrac{12x+8}{5}\)

Now to find \(g(f(1)):\)

\(g(f(1))= \dfrac{12(1)+8}{5}\)
\(= \dfrac{12+8}{5}\)
\(= \dfrac{20}{5}\)
\(= 4\)

Answer 7

@Hero thank you so much!

Answer 8

Actually, the algebra is correct but I made a typo...For this problem, you put f(x) into g(x)...

The last thing I want to do is confuse you.

Answer 9

Oh okay, I understand
