What is the average rate of change over the interval [0, 4]?
choli [55]

Answer:

\frac{3}{4}

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

f(0) = 0 (when x = 0, y = 0)

f(4) = 3 (when x = 4, y = 3)

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

Where,

a = 0, f(a) = 0

b = 4, f(b) = 3

Plug in the values into the formula for average rate of change.

= \frac{3 - 0}{4 - 0}

= \frac{3}{4}

Average rate of change = \frac{3}{4}

The equation of a line is y = 2x + 3. What is the equation of the line that is parallel to the first line and passes through (2,
Masja [62]

Answer:

y = 2x - 5

Step-by-step explanation:

The slope for a parallel line is the same as the slope in the given equation.  Therefore the slope of the new line will be 2    m= 2

use that slope and (2, -1) to find b

-1 = 2(2) + b

-1 = 4 + b

-5 = b

Plug m and b into y = mx + b

y = 2x - 5
