Andru [333]

Answer:

f^{-1}(x)=4x+20

Step-by-step explanation:

<u>Given</u>

<u />f(x)=\frac{x}{4}-5\\ \\y=\frac{x}{4}-5

<u>Swap x and y and solve for y</u>

<u />y=\frac{x}{4}-5\\ \\x=\frac{y}{4}-5\\ \\x+5=\frac{y}{4}\\ \\4(x+5)=y\\\\y=4x+20

<u>Final answer</u>

<u />f^{-1}(x)=4x+20

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.

Using the order of operations, what would be the first step:<br><br> 4−8÷1−3[3+(7−5)2]
jeka94

Answer:

(7-5)

Step-by-step explanation:

According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.

Next would be [3+(2*2)]

Then, [3+4]

Then, -8/1

Then, -3(7)

So the question would be 4-8-21

Which gives you -25 as an answer.

I realize that you weren't asking for the whole thing but maybe there are follow up questions.
