Write the exponential function whose graph passes through the given points.
(0, 2) and (4, 32)

• y = 2(2)^x
• y = 2(4)^x
• y = 4(2)^x

Rewrite the equation into logarithmic form:
6² = 36

• log₆ 2 = 36
• log₆ 36 = 2
• ln 36 = 2
• 6³⁶ = 2

Rewrite the equation in exponential form:
log₉ 1/81 = -2

• ln -2 = 1/81
• -2^1/81 = 9
• 9^-2 = 1/81
• 9^1/81 = -2
