Let's consider two functions: f(x)=3x+2 and g(x)=5x−1. What is the difference between these two functions when x=4?
Second, find the difference between these two functions. That is, calculate g(4)−f(4)=19−14.
Step 1 :First, substitute x=4 into each function. For f(x), we get f(4)=3∗4+2=14. For g(x), we get g(4)=5∗4−1=19.
Step 2 :Second, find the difference between these two functions. That is, calculate g(4)−f(4)=19−14.
