F(3) means x =3 and x = 3 > -1 (f(x) = x^2 if x > -1)
so
f(3) = x^2 = 3^2 = 9

Does each equation represent exponential decay or exponential growth?

agasfer [191]

An exponential equation is represented as: $\mathbf{y = ab^x}$ , where b represents rate

Exponential growth: $\mathbf{y = 5(7)^x}$ , $\mathbf{y = 3(4.2)^x}$ and $\mathbf{y = 0.6(1.3)^x}$
Exponential decay: $\mathbf{k = 4.2(0.28)^x}$
Neither: $\mathbf{h(x) - 3x + 1.3}$

An exponential equation is said to represent growth, if the rate is greater than 1, while it represents decay if the rate is less than 1.

This means that:

$\mathbf{y = 5(7)^x}$ , $\mathbf{y = 3(4.2)^x}$ and $\mathbf{y = 0.6(1.3)^x}$ represent exponential growth because 5, 4.2 and 1.3 are greater than 1

Also,

$\mathbf{k = 4.2(0.28)^x}$ represents exponential decay because 0.28 is less than 1

While

$\mathbf{h(x) - 3x + 1.3}$ is not an exponential function
