Calculate the average rate of change of the function f(x) = 3x2 over the interval 1 ≤ x ≤ 5.
RideAnS [48]

Answer:

18

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

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

here [ a, b ] = [ 1, 5 ]

f(b) = f(5) = 3 × 5² = 75

f(a) = f(1) = 3 × 1² = 3, hence

average rate of change = \frac{75-3}{5-1} = \frac{72}{4} = 18

Answer:

B

3y + 4 = -2

3y = -2 - 4

3y = -6

y = -6/3

y = -2

THus, this equation has only 1 solution. B is correct
