Question

consider the following piece - wise defined function. $f(x)=\begin{cases}\frac{3}{4}x - 3&if x < 4\\x + 5&if xgeq4end{cases}$ step 1 of 3: evaluate this function at $x = 7$. express your answer as an integer or simplified fraction. if the function is undefined at the given value, indicate \undefined\. answer selecting a radio button will replace the entered answer value(s) with the radio button value. if the radio button is not selected, the entered answer is used. $f(7)=square$ 〇 undefined

Explanation:

Step1: Determine the correct part of the function

Since \(x = 7\geq4\), we use \(f(x)=x + 5\).

Step2: Substitute \(x = 7\)

Substitute \(x=7\) into \(f(x)=x + 5\), we get \(f(7)=7 + 5\).

Step3: Calculate the result

\(7+5=12\).

Answer:

\(12\)
