Answer:

(a)x=2

(b)f(16)=56

Explanation:

Part A

Given the function f(x) defined as follows:

[tex]f\mleft(x\mright)=3x+5[/tex]

When f(x)=11, we have:

[tex]11=3x+5[/tex]

We solve for x.

[tex]\begin{gathered} 11-5=3x \\ 6=3x \\ x=\frac{6}{3} \\ x=2 \end{gathered}[/tex]

Part B

Given the function f(x) defined as follows:

[tex]f\mleft(x\mright)=4x-8[/tex]

When x=16

[tex]\begin{gathered} f\mleft(16\mright)=4(16)-8 \\ =64-8 \\ =56 \end{gathered}[/tex]
