Question

Consider the linear function f(x)=4-0.5x. Find and simplify the expression for y=f(x+6).

Answer 1

wow thats tough

Answer 2

Replace every `x` with `x+6`
\[\Large f(x)=4-0.5x\]
\[\Large f(x)=4-0.5(x)\]
\[\Large f(\color{red}{x})=4-0.5(\color{red}{x})\]
\[\Large f(\color{red}{x+6})=4-0.5(\color{red}{x+6})\]
I'll let you simplify
