Determine the intercepts of the line.
Andreyy89

Answer:

y intercept: (0, 26)

x intercept: (-13/2, 0)

Step-by-step explanation:

Simplify to y = 4 x + 26

then set x=0 to get the y intercept:

y = 4*0 + 26

then set y=0 to get the x intercept:

0 = 4x + 26 =>

x = -26/4 = -13/2

Find the inverse of the function.<br> y=3x–5
PIT_PIT [208]

Step-by-step explanation:

it means that x has now to be the result variable, and y the input variable.

so,

y = 3x - 5

y + 5 = 3x

x = (y + 5)/3

and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get

y = (x + 5)/3

as the inverse function
