Joel was given instructions to observe, measure and grade this sprinkler (see Figure 1). Holes need to be spaced 15mm apart, but the company can accept a 1mm allowance either way. Joel left his notes
highlighting sections A and B. Examine Figure 1 and tell what you think your measurements of sections
A and B would be (don't use a ruler). Explain why you gave the answers you did.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
