Don you mean find its inverse function??
If so, then you can determine if a function has an inverse by passing the "horizontal line test."
This function does because it has a slope not equal to zero. Inverses of horizontal lines have vertical lines in them, which are not by definition functions.
So now, simply replace "f(x)" with "y", then switch the x and y, and solve for y:
y = 5x + 1
x = 5y + 1
-1 -1
5y = x - 1
÷5 ÷5
y = (x-1)/5

The easiest way to find the inverse of a function is to swap the x and y, meaning:

We have the function f(x)=5x+1. Let's call our outputs "y", so we have y=5x+1. To find the inverse, we're going to change the x and the y's position in the equation, so we have x=5y+1. Then all we need to do is solve for y:
x=5y+1
x-1=5y
\frac{x}{5}-\frac{1}{5}=y
f^{-1}(x)=y=\frac{x}{5}-\frac{1}{5}

The altitude of an equilateral triangle is 9 inches. Find the perimeter of the triangle in inches.
Fiesta28 [93]
If we  draw a perpendicular line from one of the vertices of the triangle we get  2 right angled triangles  each with  altitude 9 ins  and vertex angle = 30 degrees.   So:-

cos 30 = 9 /h     where h = one of the sides of the equilateral triangle

h =  9 / cos 30  =  10.392 inches

Therefore the perimeter of the triangle = 3 * 10.392 =  31.1769 ins

Answer is 31.18 inches to the nearest hundredth.

apex if you put down 15% on a $9000 car and pay monthly payments of $189.40 for 48 months what is the total price of the car
defon

The total amount payable for the car if you put a down 15% on a $9000 car and payment of $189.40 for 48 months will be:

Amount=(15/100×9000)+(189.40×48)

=1350+9091.2

=10,441.2

The total amount of money paid for the car after a period of time will be $10,441.2
