Question

Given g(t)= -t+5, what is the value of g(-15)?

Answer 1

We have that
`g(t)=-t+5`, and we are asked to evaluate
`g(-15)` . In notation of functions like this, the number inside the parentheses is the value of the variable. Or, to be more clear, this is essentially telling us that
`t=-15` for our expression
`g(t) = -t+5`. So we can evaluate it as follows:

`g(-15) = -15 + 5 = -10`
