Answer:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
Answer:
Step-by-step explanation:
Total points needed for two tests to average 90 is 90 x 2 = 180 points.
Subtract the score of the first test from the total points needed:
180 -95 = 85
She needs an 85 on the second test.

Quadratic function describes the graph of a parabola and they are formed by a quadratic term () a linear term () and a constant number (c). Quadratic terms have an exponent of 2 and linear terms have an exponent of 1.
For this situation, we have only the quadratic term () which is enough to know that there is a quadratic function.
Have a nice day!
Product indicates that we need to multiply. We can multiply 2xy+3 by x-4 using the distributive property in which we multiply each term of one polynomial by each term in the other:
(2xy+3)(x-4) =
2x^2*y - 8xy + 3x - 12
The answer is 60.
You must first solve what is in parentheses.
