Find the inverse function
Alex

The inverse of this function is f(x) = \frac{3x + 15}{4}


To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.


f(x) = \frac{-15 + 4x}{3} ----> Switch the x and f(x)


x = \frac{-15 + 4f(x)}{3} ----> Muliply both sides by 3


3x = -15 + 4f(x) ----> Add 15 to both sides


3x + 15 = 4f(x) ----> Divide both sides by 4.


f(x) = \frac{3x + 15}{4}

bija089 [108]
A parallelogram

Because...
-opposite angles are congruent
-four sides
-angles must equal 360
       100 + 100 +80 + y = 360

       280 + y = 360

       y = 80
-the angle we don't know is 80 degrees
