Classify each equation as exponential growth or exponential decay. Sketch the curve.

1. f(x)=1/2 * 5^x

2. f(x)=(6/5)^x

3. f(x)=4 * (3/8)^x

I think the first one is growth but I'm not sure. Please show any work because I need to understand this. Thank you.

1 as x gets bigger so does 5^x and so does the expression : Growth

2 as x gets bigger so does (6/5)^x Growth

3 As x gets bigger 3/8 ^x gets smaller decay

if the number that is raised to the 'x' power is greater than 1 growth

if the number is less than one decay
