Answer:
1 C (greatest)
2 D
3 B
4 A (least)
Explanation:
A positive slope is at points where y increases as x increases. A negative slope is when y decreases as x increases. A zero slope is at the turning points of the graph either at a minimum or maximum
There are 2 points where the slope is positive C and D. If you look at point C the graph increases at a sharper rate than point D. Sol we know that slope of C > slope of D
At point A slope is negative and at point B it is zero since the slope is changing from negative to positive at this point. This is a minimum
any negative number is less than 0 less than any positive number
hence
slope(C) > slope(D) > slope(B) > slope(A)
