Answer:
Step-by-step explanation:
Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%
The expression which represents the function required to be generated; (f +g)(x) as in the task content is; 13x -2.
<h3>What is the expression which represents the function required?</h3>
It follows from the function definitions in the task content that the functions given are;
f(x) = 4x +5
g(x) = 9x -7
Hence, the value of (f +g)(x) = f(x) + g(x) and ultimately;
= 4x +5 + 9x -7
= 13x -2
