Question

Hello, the three problems below is what I need help with.Use the given functions solve:f(x)= 6x+7. g(x)= -2x-4. h(x)= -3x/4Answer:1. f(x-2)2. g(7x+1)3. h(-12)

Answer 1

`\begin{gathered} f(x-2)==6x-5 \\ g(7x+1)=-14x-6 \\ h(-12)=9 \\ \end{gathered}`

Step-by-step explanation

you have to replace the values in each function

Step 1

`\begin{gathered} f(x)=6x+7 \\ f(x-2)=6(x-2)+7=6x-12+7=6x-5 \\ f(x-2)==6x-5 \\ \end{gathered}`

Step 2

`\begin{gathered} g(x)=-2x-4 \\ g(7x+1)=-2(7x+1)-4 \\ g(7x+1)=-14x-2-4 \\ g(7x+1)=-14x-6 \end{gathered}`

Step 3

`\begin{gathered} h(x)=(-3x)/(4) \\ h(-12)=(-3\cdot-12)/(4) \\ h(-12)=(36)/(4) \\ \\ h(-12)=9 \end{gathered}`

I hope this helps you
