Question

Two functions are shown. f(x) = 29(0.5)" g(x) = 18x + 14 What is the value of f(2) + g(4)? A. 7.25 B. 25 C. 86 D. 93.25

Answer 1

The given functions are:

`\begin{gathered} f(x)=29(0.5)^x \\ g(x)=18x+14 \end{gathered}`

So the value of f(2):

`\begin{gathered} f(2)=29(0.5)^2 \\ f(2)=7.25 \end{gathered}`

And value of g(4):

`\begin{gathered} g(4)=18(4)+14 \\ g(4)=86 \end{gathered}`

Now the value of f(2)+g(4) is:

`\begin{gathered} f(2)+g(4)=7.25+86 \\ f(2)+g(4)=93.25 \end{gathered}`

So the correct option is D.
