This was taken from a source, but I hope it helped out! Have a nice day :)
(The answer is in the bottom of the picture)
F(x)=x
Domain: 1 2 3 4 5 6
Range: 1 2 3 4 5 6
F(x)=2x
Domain: 1 2 3 4
Range: 0 2 4 6
X intercept: (-4)
y intercept: (8)
X = log (base b) y
The base of the log becomes the base of the exponent.
The x and y switch.
b^x = y
