Find the inverse of the function.
y= √x - 4

The inverse is (x) =

Step-by-step explanation:

(By the way, (x) is f negative one of x, like f(x), but inverse)

f(x) = - 4 is the same as y = - 4

y = - 4               start with the equation.

x = - 4               switch x and y.

x + 4 =              add 4 to both sides.

= y             square both sides.

(x) =    change y to the inverse f(x) format.

I hope this helps! :)

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
