Question

Select the correct locations on the image.

Select function f and function g such that the sum of f and g is function h.

Answer 1

f(x) = -2x + 3

g(x) = 7x - 9

f(x) + g(x) = -2x +3 + 7x - 9

f(x) + g(x) = 5x -6 = h(x)

Explanation:

Answer 2

This has to be done by hit and trial method. i.e. you have to checking adding which of the function from first column to function in second column will yield h(x).

The following functions yield given value of h(x).

f(x) = -2x + 3
g(x) = 7x - 9

f(x) + g(x) = -2x +3 + 7x - 9
f(x) + g(x) = 5x -6 = h(x)

So, from 1st column its the cell number 3, and from the second column its the cell number 2.
