Consider the graph of the quadratic function. which interval on the x-axis has a negative rate of change?
answers:
a. –2 to –1b. –1.5 to 0c. 0 to 1d. 1 to 2.5

The average rate of change is defined as:

For AVR to be negative, it must comply with:

Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.

Among the options given, this interval is:

1 to 2.5

An interval on the x-axis that has a negative rate of change is:

D. 1 to 2.5

The rate of change of a graph is positive when the graph is increasing from left to right and it is negative when it is decreasing from left to right

Reasons:

Rate of change is given by the equation;

Which gives;

In the range where the graph is decreasing from left to right, we have in the x-axis interval, 1 to 2.5, the points (1, 3), and (2.5, -1)

Therefore;

Therefore, the rate of change of the quadratic function in the x-axis interval 1 to 2.5 is , which is negative;

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
