(a) Given f(x) = x2. Find the average rate of change between x1 = 3 and x2 = 7 (b) Given k(t) = t2 + 4t - 5. Find the average rate of change between t1 = 1 and t2 = 3

Use the formula, A. R.C. = f(x2) - f(x1)
x2 - x1

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

probably .5

i can on others if necessary.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
