Question

Will the graph y=2(4)^x be increasing or decreasing? Explain how u know

Answer 1

Explanation:

Decreasing.

This is because the as you increase the X value and solve for Y, the Y value decreases.

For example:

`x=1 \\y=2((1)/(3) )^1\\y=(2)/(3) =0.667\\\\x=2\\y=2((1)/(3) )^1\\y=(2)/(9)=0.222\\\\x=3\\y=2((1)/(3) )^3\\y=(2)/(27)=0.074`
