Given the equation f(x)=-2x²+4x+6 find the average rate of change from x=1 and x=2

emmainna [20.7K]

Answer:

Step-by-step explanation:

1) Plug x=1 into equation

f(x) = -2(1)²+4(1)+6

f(x) = -2²+4+6

f(x) = 4+4+6

y = 14

(1,14)

2) Plug in x=2 into equation

f(x) = -2(2)²+4(2)+6

f(x) = -4²+8+6

f(x) = 16+8+6

y = 30

(2,30)

3) Use slope formula ( $\frac{y2-y1}{x2-x1}$ )

$\frac{30-14}{2-1}$

$\frac{16}{1}$
