Question

For the function y = 4x – 11, what is the output when the input is 10?

Answer 1

Hi there! The answer is 29.

y = 4x – 11
The input of the function is 10, so we should substitute 10 on the place of x.

y = 4(10) - 11
Multiply first.

y = 40 - 11
Subtract.

y = 29
Therefore the output is 29.
