Question

F(a)= 4a - 5

ga)= a-4

Find f(-10) + (-10)

A. 45/14
B. 19
C. 35/6
D. 14/45

Answer 1

After substituting -10 into the function f(a) = 4a - 5, and adding -10, the result is -55, which does not match any of the provided options.

Step-by-step explanation:

To solve for f(-10) when f(a) = 4a - 5 and then add (-10) to the result, we substitute a with -10 in the function:

f(-10) = 4(-10) - 5
= -40 - 5
= -45.

Now adding -10:

-45 + (-10)
= -55.

Therefore, f(-10) + (-10) is -55, which is not one of the options provided (A. 45/14, B. 19, C. 35/6, D. 14/45). Either the function provided is incorrect, or there may be an error in the question itself.
