Given: 48 students took the exam.

A total of 18 + 10 = 28 students scored 80% or above.

To find the percentage, take the part (28 students) divided by the whole (48 students) then multiply the quotient by 100.

(28 students / 48 students) x 100 = 58.33%

58.33% of the students who took the exam scored an 80% or higher

Which graph shows a negative rate of change for the interval 0 to 2 on the x-axis?
valentina_108 [34]

It seems that the four graphs are the same and they do not have a negative change rate in the interval 0 to 2 in the x-axis.

A negative change rate means that when x increases the value of the function (y) decreases; this is, the function is decreasing in the interval being estudied, which is the same that going downward.

So, you must look for in your graphs where the equation is going downward.

For example, in the graph attached, that happens in any interval from negative infitity to  1.5.

The vertex will help you to identify it.

Given that the graph goes downward from negative infinity to the vertex, any interval that includes that range will have negative change.

You must look for a parabola that opens upward and whose vertex is in x = 2.
