Does the function represent exponential growth or exponential decay. Identify the growth or decay factor. y=9 x (1/2)

Question

I'm not sure how to make the chart to show the decay.

Answer 1

If you mean y = 9x^1/2 it is not even exponential. An exponential function has x in the exponent, such as

y = 9 * (1/2)^x

which would be decay, because powers of fractions get progressively smaller.

If you don't know how to even make a chart, you are in trouble. For a chart, just pick values of x and evaluate the corresponding y. Then, uh, put them in the chart!
