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

3.19 become 3.20 . 1.69 becomes 1.70. Then 3.20 plus 1.70 is 4.90 or 4.9.
Answer: The required value is
Step-by-step explanation: The given functions are:
We are given to find the value of
We know that, if s(x) and t(x) are any two functions of a variable x, then we have
Therefore, we have
Thus, the required value is
