If the rate of change is the same on the entire graph we say it has a rate of change.

Constant

Step-by-step explanation:

For a straight line for example,

Take any two points from the line and find the slope,

it will be the same value for any 2 points chosen

So throughout the graph, the slope/rate of change is not changing

That is

Throughout the graph rate of change/slope is constant

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
