Let f(x) = 3 − x . Find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single fa
Ivanshal [37]

Answer:

The average rate of change of f(x) from x = a to x = a + h is -1

Step-by-step explanation:

Average rate of the function f(x) over [a, b] is given by:

A(x) = \frac{f(b)-f(a)}{b-a}

Given the function:

f(x) = 3-x

At x=a

f(a) = 3-a

At  x = a+h

then;

f(a+h) = 3-(a+h) = 3-a-h

Using the formula for average rate of function:

A(x) = \frac{f(x+h)-f(x)}{x+h-x}

Substitute the given values we have;

A(x) = \frac{3-a-h-(3-a)}{x+h-x}

Simplify:

A(x) = \frac{3-a-h-3+a}{h}

or

A(x) = \frac{-h}{h} = -1

Therefore, the average rate of change of f(x) from x = a to x = a + h is, -1

What is the intercepts. 4x+8y=32
Alik [6]

4x + 8y = 32

To find the x-intercept, replace y with 0.

4x + 8(0) = 32

Then simplify to find x.

4x = 32

4x/4 = 32/4

x = 8

To find the y-intercept, replace x with 0.

4(0) + 8y = 32

Then simplify to find y.

8y = 32

8y/8 = 32/8

y = 4


x-intercept = (8, 0)

y-intercept = (0, 4)
