Q. Use the following function rule to find f(−9q). Simplify your answer.f(j)=8jf(−9q)=__
Identify Function Rule: Identify the function rule and the input value.The function rule given is f(j)=8j, and we need to find the value of f(−9q).
Substitute Input Value: Substitute −9q for j in the function rule.Using the function rule f(j)=8j, we substitute j with −9q to find f(−9q).f(−9q)=8(−9q)
Simplify Expression: Simplify the expression.Now we multiply 8 by −9q to simplify the expression.f(−9q)=8×−9qf(−9q)=−72q
