Let f (x) = -1/2(x + 2)+ 5

bogdanovich [222]

Answer:

Rate of change = -1

Step-by-step explanation:

Given:

f(x) = -½(x + 2)² + 5

Required:

Average rate of change from x = -3 to x = 1

Solution:

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

Where,

a = -3,

f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5

b = 1,

f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5

Plug in the values into the formula:

Rate of change = $\frac{0.5 - 4.5}{1 - (-3)}$

Rate of change = $\frac{-4}{4}$

Rate of change = -1

Eddi Din [679]

$6x {y}^{2} = (3x)(2 {y}^{2} )$

$25 {a}^{3} {b}^{2} = (5 {a}^{2} {b}^{2} )(5a)$

$6x + 6y + 6p =( 6)(x + y + p)$
