Question

Help me pls will give out points

Answer 1

$y = ab^{x}$

$y = 3 \times {4}^{x}$

"a" is the initial amount (3), and "b" is the growth factor (4).

To find "b" plug in the knowns into the exponential function equation and solve.

$y = ab^{x}$

$48 = 3 \times {b}^{2}$

$16 = {b}^{2}$

$\sqrt{16} = b$

$b = 4$
