Need answer desperately
in order for the function to be linear, what must m be and why?

m = 22 because the rate of change is 1.
m = 20 because the rate of change is 3.
m = 22 because the rate of change is –1.
m = 20 because the rate of change is –3.

The correct option is 4.

Step-by-step explanation:

If a line passing through two point, then the slope of the line is

From the given table it is clear that the line passing through the points (4,26), (5,23) and (6,m).

Line passing through (4,26) and (5,23). So, the slope of the line is

The slope of line is -3.

Line passing through (4,26) and (6,m), and the slope of the line is -3.

Multiply both sides by 2.

Add 26 on both the sides.

The value of m is 20 and because the rate of change is –3.

Therefore the correct option is 4.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

its kinda hard to answer this when we dont have all the information that we need.
