Reflection over the y-axis.

When multiplying exponential terms with the same base, add the exponents: $b^m * b^n = b^{m+n}$.

When raising an exponential term to a power, multiply the exponents: $(b^m)^n = b^{mn}$.

A negative exponent indicates the reciprocal of the base raised to the positive value of the exponent: $b^{-n} = \frac{1}{b^n}$.

An exponential unit fraction, like $b^{1/k}$, represents the kth root of b. The value of $b^{1/k}$ is the kth root of b, when it exists.

A horizontal translation of an exponential function, $f(x) = b^{x+k}$, is equivalent to a vertical dilation, $f(x) = ab^x$, where $a = b^k$.

A horizontal dilation of an exponential function, $f(x) = b^{cx}$, is equivalent to changing the base, $f(x) = (b^c)^x$.

Reflecting the graph of $f(x) = b^x$ over the y-axis gives the graph of $f(x) = b^{-x} = \frac{1}{b^x}$.

If the base were negative, the function would oscillate between positive and negative values. If the base were 1, the function would be constant. If the base were 0, the function would be undefined for negative exponents.

Understanding transformations helps analyze and predict the behavior of exponential functions under various conditions, which is crucial for modeling real-world scenarios.

The square root of a negative number is not a real number because no real number multiplied by itself yields a negative result.

A larger value for $b$, indicating faster exponential growth.

A leftward shift increases the y-intercept, while a rightward shift decreases it.

It transforms the graph into that of $f(x) = (1/b)^x$, changing growth to decay.

It multiplies the y-intercept by the dilation factor.
