Question

F(a) = 5a 3 + 10a 2 - 18a - 7 at a = -3

Answer 1

To find the value of f(a) at a = -3, plug -3 into the function and perform the arithmetic operations following order of operations.

Step-by-step explanation:

To evaluate the function f(a) = 5a^3 + 10a^2 - 18a - 7 at a = -3, you need to substitute -3 for a and calculate the value of the function.

Here are the steps for the substitution:

1. Replace each occurrence of 'a' in the function with -3.
2. Calculate the powers of -3: (-3)^2 and (-3)^3.
3. Multiply these values by their respective coefficients in the function.
4. Add or subtract all values obtained after calculation.
5. The result is the value of f(-3).

Note: The specific values and expression provided in the question (5a 3 + 10a 2 - 18a - 7) appear to have typos. It should be interpreted as f(a) = 5a^3 + 10a^2 - 18a - 7.
