Question

f(x) = 5x + b = For the linear functionf, b is a constant and f (1) = 16. What is the value of b?

Answer 1

SOLUTION

We have been given that

$\begin{gathered} f(x)=5x+b \\ \text{and that } \\ f(1)=16 \end{gathered}$

So, this means that

$\begin{gathered} f(1)=16=5(1)+b \\ \text{hence } \\ 16=5(1)+b \\ 16=5+b \\ b=16-5 \\ b=11 \end{gathered}$

Hence, the answer is b = 11
