Question

Given,g(x) = -4x - 5f(x) = 2x - 5Find ((4))

Answer 1

Given

f(x) = 2x - 5

g(x) = -4x - 5

Find

g(f(4))

Step-by-step explanation

first we will find the value of f(4)

`\begin{gathered} f\mleft(x\mright)=2x-5 \\ f(4)=2(4)-5=8-5=3 \end{gathered}`

so ,

g(f(4)) = g(3)

`\begin{gathered} g(f(4))=g(3) \\ g(f(4))=g(3)=-4(3)-5=-12-5=-17 \end{gathered}`

Final Answer

Hence , the value of g(f(4)) is -17
