Question

Given the function g(x)=-4x+5, find g(-4)

Answer 1

-11?

Answer 2

This function says that when you plug in the value of x, you get -4 times that number and 5 more. If we put -4, then we'll get -4 times the number and 5 more.

\(\Large \color{purple}{\rightarrow g(-4) = -4(-4) + 5 }\)
\(\Large \color{purple}{\rightarrow g(-4) = 16 + 5 }\)
\(\Large \color{purple}{\rightarrow g(-4) = 21 }\)
