Question

4 multiple choice 1 point
which of the following is the correct form for an exponential function:
$y = a \cdot b^x$
$y - y_1 = m(x - x_1)$
$y = mx + b$
$ax^2 + bx + c$

Explanation:

• $y = a \cdot b^x$ is the standard form of an exponential function, where $a$ is the initial value, $b$ is the base ($b>0, b

eq1$), and $x$ is the exponent.

• $y - y_1 = m(x - x_1)$ is the point-slope form of a linear function.
• $y = mx + b$ is the slope-intercept form of a linear function.
• $Ax^2 + Bx + C$ is the standard form of a quadratic function.

Answer:

A. $y = a \cdot b^x$
