What is the average rate of change of the function f(x)= x^2 -3 from x=1 to x=2?

3

Step-by-step explanation:

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

Here [ a, b ] = [ 1, 2 ]

f(b) = f(2) = 2² - 3 = 4 - 3 = 1

f(a) = f(1) = 1² - 3 = 1 - 3 = - 2, thus

average rate of change = = 3

3

Step-by-step explanation:

Average rate of change

= [f(2)-f(1)] ÷ (2-1)

= [(2²-3) - (1²-3)] ÷ 1

= (4-3) - (1-3)

= 1 - (-2)

= 1 + 2

= 3

no this is a nonlinear negative

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
