Step-by-step explanation:
B) 1 and 13 are x intercepts so true
D) greatest profit is when price is 7; after that profit is getting smaller because function is decreasing
The rate of change of a line is regarded as the slope/ gradient (m) of the line
The slope/ gradient (m) of the line moving through points (x₁,y₁) and (x₂,y₂) is given as

On substituting the above values in the formula above we will have the slope to be

Therefore,
The rate of change of the line through (2,3) and (3,8) is 5
32,000 and 42,000. I know this because the question states "Two Thousands." 32,000 and 42,000 are both two thousands because 32 and 42 both end with 2's because of the "Two" in "Two Thousand."
