How would you solve for x? For some reason I just can't figure them out... I greatly appreciate anyone who could help me :)

#1) y= √x

y = x^2

#2) y=e^-x

y=e^x

#3) y=4-x^2

y=1-x^2

#4)

y=e^x

y=ex

#5) y=x^3-3x+1

x+y

Although you said continue here and I can see your process....I don't know how to continue forward. It looks to me like x isn't being solved for. I don't understand what I am doing wrong. Please help...thank you to anyone who can

1) Factor. Apply

**the difference-of-cubes formula**to x^3 - 1. Solve the two linear factors.

2) To learn how to solve exponential equations, try**here**. (Wink)
