Y = 5x^2 - 10<br> what is the rate of change ?<br> is the function linear or non linear ? why ?

Svetlanka [38]

Answer:

Step-by-step explanation:

Are you in Calculus? These are calculus concepts!

To calculate the rate of change here you must specify an interval, e. g., "what is the rate of change on the interval (0, 3)?"

If you know calculus: The 'rate of change' on the interval (a, b) is

f(b) - f(a)

r. of c. = --------------------

b - a

Have you used this formula before?

Because of the 'x^2' term this is NOT a linear function.

If you want more explanation, provide an interval on which you want the average rate of change and ask specific questions of your own.
