To find the value of f(5), substitute 5 for a in the given equation f(5) = 3(a+2)-1. The resulting value of f(5) is 20.
Step-by-step explanation:
To find the value of f(5) when f(5) = 3(a+2)-1, we substitute 5 for a in the equation.
f(5) = 3(5+2)-1
f(5) = 3(7)-1
f(5) = 21-1
f(5) = 20
Therefore, f(5) is equal to 20.
