Answer:
19
Step-by-step explanation:
Operations of functions:
h(x) = f(z) + g(z)
h(x) = (2z³ - 3z) + (-3z² + 1)
Simplify or expand:
(2z³ - 3z) + (-3z² + 1)
Determine the sign
2z³ - 3z - 3z² + 1
Rewrite the expression
2z³ - 3z² - 3z + 1
Calculate:
Substitute z = 3 into
2z³ - 3z² - 3z + 1
Substitute
2 × 3³ - 3 × 3² - 3 × 3 + 1
Calculate
