You are given the function

 We will evaluate f(3) – f(–1). Which half of the formula for f(x) do we use for evaluating at x = 3? ??? the first half 3 -1 1 6 7 the second half Fill in the blank:  f(3) = [___] + 4 ??? the first half 3 -1 1 6 7 the second half Choose the correct value:  f(3) = ___ ??? the first half 3 -1 1 6 7 the second half Which half of the formula for f(x) do we use for evaluating at x = –1? ??? the first half 3 -1 1 6 7 the second half Fill in the blank:  f(–1) = 2[___] 2 – 1 ??? the first half 3 -1 1 6 7 the second half Choose the correct value:  f(–1) = ___ ??? the first half 3 -1 1 6 7 the second half Then f(3) – f(–1) = [___] ??? the first half 3 -1 1 6 7 the second half
