I'm pretty sure you just have to carry over the x to the f and g to make it fx-gx and then just plug in the numbers and do the equation.

Over which interval does f have an average rate of change zero?
kvv77 [185]

Answer:

Step-by-step explanation:

The average rate of change is the slope. Slope has a formula that is the change in y over the change in x, which is a fraction. The only time a fraction can have a vlue of 0 is where the numerator of the fraction is equal to 0 (since we are not allowed to have a denominator of 0). If the change in y is in the top of the slope fraction, then we have to find the interval where the y values are the same. I'll show you one where the y values are not the same so you can compare it to the slope where the y values are the same. We will find the slope of choice A.

When x = -3, y = 0 so the coordinate is (-3, 0).

When x = 5, y = 5 so the coordinate is (5,4). Now let's find the slope (aka average rate of change) between those 2 coordinates:

m=\frac{4-0}{5-(-3)}=\frac{4}{8}=\frac{1}{2}  and the top of the fraction is a 1, not a 0, so the average rate of change between these 2 points is 1/2, not 0. Now let's do D.

When x = -3, y = 0 so the coordinate is (-3, 0).

When x = -1, y = 0 so the coordinate is (-1, 0). The slope between these 2 points is

m=\frac{0-0}{-1-(-3)}=\frac{0}{2}=0 This fraction is equal to 0 because the numerator is 0. Choice D is the one you want.

What’s 4/5 times 2/3
maxonik [38]

Answer:

8/15

Step-by-step explanation:

When multiplying fractions, simply multiply the numbers straight across. First, multiply the numerators to get 8. Then, multiply the denominators and you'll get 15.
