Question

Use the following function rule to find f(4).
f(x) = 9x + 1
f(4) =
Submit

Answer 1

Answer: f(4) = 37

Explanation:

We need to calculate
`\sf{f(x)=9x+1}`. To find f(4), we will substitute 4 into the function:

`\sf{f(4)=9(4)+1}` {multiply}

`\sf{f(4)=36+1}` {add}

`\sf{f(4)=37}` {result}

Therefore, f(4) = 37.
