Given f(x)= 3x+2, what is the Inverse Function?
Grace [21]

Answer:

Step-by-step explanation:

For this case we must determine the inverse of the following function:

f(x)=3x-2

Step 1:

We would write

y=f(x) or y=3x-2

Step 2:

We clear x:

y+2=3x

\frac{y+2}{3}=x

Step 3:

"x" and "y" are exchanged:

y=\frac{x+2}{3}

The inverse is:

f^{-1}(x)=\frac{x+2}{3}

Find the slope of segment AB, A (2,18), B (-2,4)
MariettaO [177]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points A(2, 18) and B(-2, 4). Substitute:

m=\dfrac{4-18}{-2-2}=\dfrac{-14}{-4}=\dfrac{14}{4}=\dfrac{7}{2}
