Given:

The function is:

f(x)=6x-3

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

f(x)=6x-3

Step 1: Substitute f(x)=y.

y=6x-3

Step 2: Interchange x and y.

x=6y-3

Step 3: Isolate variable y.

x+3=6y

\dfrac{x+3}{6}=y

Step 4: Substitute y=g(x).

\dfrac{x+3}{6}=g(x)

Therefore, the inverse of the given function is g(x)=\dfrac{x+3}{6} and the graphs of these functions are shown below.

What is the slope of the line created by this equation?<br> y-6 = -3(x--8)<br> Help!
aliya0001 [1]

Rewrite the equation in slope intercept form:

Y -6 = -3(x - -8)

Use the distributive property on the right side first:

Y -6 = -3x -24

Add 6 to both sides

Y = -3x -18

The slope is the number in front of the x variable.

Slope = -3

[6 x 4(15/5)] + [2^2 + (1x-5)]

[6 x 4(3)] + [2^2 + (-5)]

[6 x 4(3)] + [4 + -5]

[6 x 12] + [4 + -5]

[72] + [4 + -5]

72 + [-1]

72 + - 1
