Compute g(-7) /

Question

Let g be the function defined by g(t) = t2 − 5

Compute g(-7) =

Answer 1

g(-7) = (-7)2-5

first multiply the -7 and 2

= -14-5

= -19

whenever you see something like f(x) = x, and they want f(7) for example, just plug that number into the equation wherever you see an x.
