Question

Does the rule y= 4*4^x  represent a linear or an exponential function? Explain.

anonymous · Answer

since the independent variable is an exponent, it is NOT linear

anonymous · Answer

A linear function would have a simple slope intercept form: y+mx+b. There wouldn't be an exponent in a linear function. So, this is exponential.

anonymous · Answer

explain please :)

anonymous · Answer

May I ask what you need explained further?

anonymous · Answer

i need explain why the equation is exponential

anonymous · Answer

There is a variable in the *exponent* . . . ?

anonymous · Answer

I used a process of elimination. Liner equations are confined to straight lines in slope intercept form (y=mx+b, as I mentioned earlier). 

You can also simply think of it as having an exponent and therefore being exponential, I suppose.
