We have that
y = 2x²<span> + 2

step 1

</span><span>exchange the value of x for y and the value of y for x
</span>y = 2x² + 2------> x=2y²+2

step 2
clear y variable
 x=2y²+2----> 2y²=x-2----> y²=[(x-2)/2]-----> y=(+/-)√[(x-2)/2]

step 3
the inverse is
f(x)-1=(+/-)√[(x-2)/2]

What is the solution to the system of equations
FromTheMoon [43]

Answer:

(0,3)

Step-by-step explanation:

solve for 2y

-X-2y= -6

2y=6+2x

substitute the given value of 2y into the equation -x-2y=-6

-x-(6+3x)= -6

solve for x

x=0

substitute the given value of X into the equation 2y=6+3x

2y=6+3×0

solve for y

y=3

the solution is (0,3)
