Answer:
We conclude that:
f(a) + 5 = a² + 8a - 5
Step-by-step explanation:
Given
The function is given by
f(x) = x²+8x-10
To determine
f(a)+5
In order to determine f(a)+5, first, we need to determine f(a).
Now substitute x = a in the function f(x) = x²+8x-10
f(a) = (a)² + 8(a) - 10
f(a) = a² + 8a - 10
Thus,
f(a) + 5 = (a² + 8a - 10) + 5
f(a) + 5 = a² + 8a - 5
Therefore, we conclude that:
f(a) + 5 = a² + 8a - 5
Answer:
Step 1
Step-by-step explanation:
The first step of the problem instantly shows a mistake. The gloves are 4% off of $30, not $4 off. Instead, the first step should be $30 - $1.2

Decay...? Read below
Step-by-step explanation:
Assuming you meant to put 20 - (1.27)x, it is decay. As the x increases, the y decreases, making it decay.
