Question

Given g(x)=-5x+2, find g(-4)

Answer 1

`\boxed{\mathtt{g(-4)=22.}}`

Explanation:

`\textsf{We are asked to identify g(-4).}`

`\textsf{-4 is the substituted value for x. We should substitute -4 into the equation as well.}`

`\large\underline{\textsf{Substitute:}}`

`\mathtt{g(-4)=-5(-4)+2.}`

`\large\underline{\textsf{Simplify the \bf{Right Side:}}}`

`\mathtt{g(-4)=20+2.}`

`\boxed{\mathtt{g(-4)=22.}}`

`\large\underline{\textsf{Note:}}`

`\textsf{Substitution will be used for problems such as these. If there is a number in the}`

`\textsf{parentheses, it will likely be used mainly for the \underline{right} side of the equation.}`

Answer 2

g(-4) = 22

Explanation:

To find g(-4), we must substitute it into the equation

We are given g(x) = - 5x + 2

g(-4) = - 5(-4) + 2

g(-4) = 20 + 2

g(-4) = 22
