Which exponential function is represented by the table?

f(x) = 2(2x)
f(x) = 0.8(0.8x)
f(x) = 2(0.8x)
f(x) = 0.8(2x)

What do you think the answer is?

u are not typing the exponential part correctly in ur choices...but i think i know what u meant ;)

two things will help u solve this prob:

$$x=0,  a^{bx} = a$$

$$x=1, a ^{bx} = a ^{b}$$

@sdfgsdfgs What you just said doesn't make any since. Walk through it. It could help. Like 
Step 1: What do you think answer is?
Step 2: Why do you think it is that answer.
Step 3: Try to help simplify 2 of the answer choices.
step 4: Help determine the answer.
Step 5. Make sure they understand.

@jaylelile  What do you think the answer is?

sdfgsdfgs · Answer

well @jaylelile hasnt posted anything so far so there is no way to tell if he understands anything at all.

what i meant about the choices being typed incorrectly is that:

f(x) = 2(2x) should be f(x)=2*(2^x)

which makes more sense as the prob specified "exponential function"

by using the two points, x=0 and x=1, one can find out the two constants a and b to solve the prob.

Okay, I see where you're going with it. Sorry for the mis-understanding.
