What you need to do is multiply both sides by the same number. If 8 times 6 is 48, then 7 times 6 is your answer.

Given the function f(x) = 4x - 2, explain and show how to find the average rate of change between x = 2 and x = 4.
zalisa [80]

Answer:

The average rate of change between x = 2 and x = 4 is of 4.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x) in an interval [a,b] is given by:

A = \frac{f(b)-f(a)}{b-a}

In this question:

f(x) = 4x - 2, b = 4, a = 2

Thus:

f(b) = f(4) = 4(4) - 2 = 16 - 2 = 14

f(a) = f(2) = 4(2) - 2 = 8 - 2 = 6

Average rate of change:

A = \frac{f(b)-f(a)}{b-a}

A = \frac{14-6}{4-2}

A = \frac{8}{2}

A = 4

The average rate of change between x = 2 and x = 4 is of 4.

Answer:

The fraction 58/60 is equal to 29/30 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (29/30) by any interger number, ie, multiply by 2, 3, 10, 30... 58/60 is equivalent to 29/30 because 29 x 2 = 58 and 30 x 2 = 60

Step-by-step explanation:

Dont know if this helps but i hope it does!
