I tried two of them but I don't think they are right. The other ones, I'm confused on how to answer them. Please help explain! Thank you.
+130116 The object is to get x by itself..then ......"swap" x and y .
y = 3x + 2 subtract 2 from both sides
y - 2 = 3x divide both sides by 3
[ y - 2 ] / 3 = x "swap" x and y
[ x - 2 ] / 3 = y so.....the inverse is in red....your answer is correct !!!
y = (2/3)x - 5
y + 5 = (2/3)x mltiply both sides by (3/2)
(3/2y + 15/2 = x
(3/2)x + 15/2 = y the inverse is in red
y = x^2 + 8 your answer is good !!!!
y = ( x + 3)^2 tke both roots
±√y = x + 3
±√y - 3 = x
±√x - 3 = y the inverse is in red
y = √ [ 2x - 3 ] square both sides
y^2 = 2x - 3
y^2 + 3 = 2x
[ y^2 + 3 ] / 2 = x
[ x^2 + 3 ] / 2 = y the inverse is in red
y = √[4x] - 7
y + 7 = √[4x] square both sides
(y + 7)^2 = 4x divide both sides by 4
(y + 7)^2 / 4 = x
(x + 7)^2 / 4 = y the inverse is in red
