Answer:

f(x) = 0, -2, 4, 18

Explanation:

It is convenient to let a graphing calculator or spreadsheet do the repetitive calculations for you. The filled-in table is attached.

Additional comment

When evaluating polynomial functions by hand, it is convenient to write them in "Horner form."

f(x) = (x +5)x +4

f(-4) = (-4 +5)(-4) +4 = -4 +4 = 0

f(-2) = (-2 +5)(-2) +4 = -6 +4 = -2

f(0) = 4 . . . . the constant term

f(2) = (2 +5)2 +4 = 14 +4 = 18

Complete the table. f(x) = x2 + 5x + 4 + f(x) -4 -2 No 2-example-1
