If f(x) = 5x − 3, which expression represents its inverse function?
tangare [24]

Answer:

f ^{-1}(x)=\frac{x+3}{5}

Step-by-step explanation:

To find the inverse of a function f (x) follow the steps below:

1) Make y = f (x)

y= 5x - 3

2) Solve for the variable x

y+3= 5x - 3+3

y+3= 5x

x=\frac{y+3}{5}

3) Exchange the variable x with the variable y

y=\frac{x+3}{5}

4) Make y = f ^{-1}(x)

f ^{-1}(x)=\frac{x+3}{5}

Finally, the inverse of the function f (x) is: f ^{-1}(x)=\frac{x+3}{5}

A line with slope 1/2 passes through the point (8, -1). What is the equation of this line?
OverLord2011 [107]
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1
