Best answer 1 1 vote Hey there bro. Let me teach you a trick to solving simple inverse functions. Let's use your question as an example. Let's switch the x and the y. This will give us $x = 4y + 5$. Now try and isolate the y again. You should end up with $y = (x-5)/4$. have fun!

0 0 votes You need to find $y$ based on $x$. $h(x) = y = 4x + 5$ $y-5= 4x$ $x = \frac{y-5}{4}$ Now, from the above equation, you can define a function which is inverse function: $g(y)= \frac{y-5}{4}$ tofighi answered Dec 5, 2019 tofighi 116k points 73 79 101 comment Share 0 reply Please log in or register to add a comment.
