anonymous · Answer

y=a(b)^k(x-d)  + C

freckles · Answer

What exactly do you want to know about an exponential function?
Like how to graph it?

freckles · Answer

$$y=a^x$$
is an exponential function if $$a \in (0,1) \cup (1,\infty)$$

anonymous · Answer

Yes I knowhow to graph using theTOV but I need help stating transformationns, the part where i have to find the horizontal compression or stretch

anonymous · Answer

For instance:y= (1/2) ^ 4(x-2)

freckles · Answer

$$y=a^x \text{ if } a>1 $$
looks like |dw:1416977536495:dw|
and $$y=a^x \text{ if } 0<a<1$$
looks like |dw:1416977563372:dw|
