Classify each equation as exponential growth or exponential decay. Sketch the curve.
1. f(x)=1/2 * 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
