Answer:
f^-1(x) is a function
Step-by-step explanation:
To get the inverse you replace f(x) with y, so you get y=3x^2+2. Then you switch your x and y to get x=3y^2+2. Now you want to solve for y, so you subtract two to get x-2=3y^2. You then divide both sides by 3 to get (x-2)/3=y^2. Finally you square root both sides to get y=√((x-2)/3). Now you get that f^-1(x)=√((x-2)/3). When you graph it you can see that the graph passes the vertical line test, so f^-1(x) is a function.
Answer:
50 meters
you have to multiply both numbers in order to find the area
Answer:
The answer is B
Step-by-step explanation:
The angle 2x and angle that has a value of 48 are vertical angles therefore they are congruent
This means that they both equal 48
so 48=2x
we just divide each side by 2
48/2=24
x=24
First you solve for X then substitute the number you got for X and then solve for Y.
