Answer:

x= 2.28

or, x= 0.219

Step-by-step explanation:

2x²-5x+1 =0

a= 2, b= -5 and c= 1

x= (-b + √(b²-4ac))/2a

= (5 + √(25-8))/4

= (5 + √17)/4

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
