What is the domain and range fro the expentiral function f(x)=2x4^x1+3?
Domain:all real numbers
Range:all real numbers less than 3
Domain:all real numbers
Range:all real numbers greater than 3
Domain: all real numbers greater than2
Range: all real numbers less than 3
Domain: all real numbers
Range: all real numbers
If the parent function is f(x) = (0.5)^x, which transformations are required for the graph of f(x) = (0.5)^x3  2?

How do I figure something like this out... I'm lost once again

Assuming you meant
f(x)=2x*4^(x1)+3
the domain of all polynomials (2x) is (∞,∞)
the domain of all exponentials is (∞,∞)
so, the domain of f(x) is likewise (∞,∞)
now work with the ranges in like wise.
x > (xh) translates right by h
y > (yk) translates up by k
y = 0.5^(x3)  2 is also
y(2) = 0.5^(x3)
so what do you think? 
Thanks Mr.Steve!
