Prove that the linear function f(x)=3x-7 changes by equal amounts over equal intervals of length 5.
Step 1: Choose two input values for z. Let's use § and s+5. We use the two values of 2 where the difference between them is 5.
Step 2: Let's solve for the output values f(s) and f(s+5). The first one is found for you. Find the other value. f(s)=3s-7
f(s+5)=3(s+5)-7=________
