Answer:
#13: 0
#14: -99
Explanation:
#13: g(x) = 2x^3 - 5x^2 + 4x - 1; x = 1
Step 1: Substitute 1 for x
2(1)^3 - 5(1)^2 + 4(1) - 1
2(1) - 5(1) + 4 - 1
2 - 5 + 4 - 1
0
Answer: 0
#14: h(x) = x^4 + 7x^3 + x^2 - 2x - 6; x = -3
Step 1: Substitute -3 for x
(-3)^4 + 7(-3)^3 + (-3)^2 - 2(-3) - 6
81 + 7(-27) + 9 + 6 - 6
81 - 189 + 9 + 6 - 6
-99
Answer: -99
