Answer:
i
Step-by-step explanation:
We can rearrange
x + y = 9
in to
y = 9 - x
This means the value of y is EQUAL to 9 minus the value of x.
[A] fits this description, because y (9) is equal to 9 minus x (0).
[B] does too, because y (0) is equal to 9 minus x (9).
Answer:
[f + (g o h)](x) = x² + 6x + 1
Step-by-step explanation:
Given functions are,f(x) = x²
g(x) = 3x + 1
h(x) = 2x
Now we have to find the value of composite function [f + (g o h)](x).
(g o h)(x) = g[h(x)]
= 3(2x) + 1
= 6x + 1
[f + (g o h)](x) = f(x) + (g o h)(x)
= x² + 6x + 1
But Jim got the answer as,
[f + (g o h)](x) = x² + 2(3x + 1)
= x² + 6x + 2
Therefore, Jim's answer was incorrect.
Correct answer will be [f + (g o h)](x) = x² + 6x + 1
