Given the function, f(x) = x^2 - 3, calculate the average rate of change of the function from x= 1 to x= 3.
Pavel [41]

The rate of change of function is: 4

Further explanation:

The formula for calculating rate of change of function is:

Rate\ of\ change = \frac{f(b)-f(a)}{b-a}

Here,

a = 1 and b = 3

So,

f(1) = (1)^2-3\\= 1-3\\=-2\\f(3) = (3)^2-3\\=9-3\\=6

Putting the values

Rate\ of\ change= \frac{f(3)-f(1)}{3-1} \\= \frac{6-(-2)}{2} \\= \frac{6+2}{2} \\= \frac{8}{2}=4

The rate of change of function is: 4

curved surface area =

perimeter of triangular base × length

= 3×8 + 12

= 24 + 12

= 36mm^2

total surface area

= curved surface area + 2× area of triangular base

= 36 + 2 × root3 ×8^2 ÷ 4

= 36 + 2 × root3 × 16

= 36 + 2× 27.71

= 36 + 55. 425
