Linear/Quadratic/Exponential
Parabola - CORRECT ANSWER >>>the U-shaped graph made by a quadratic
function
Vertex - CORRECT ANSWER >>>The lowest or highest point on a parabola. It
lies on the axis of symmetry
Axis of Symmetry - CORRECT ANSWER >>>The vertical line that cuts the
parabola in half. Starts with x =
Standard Form of a Linear Function - CORRECT ANSWER >>>Ax + By = C
Slope-intercept Form of a Linear Function - CORRECT ANSWER >>>y = mx +
b
m = slope
b = y-intercept
x-intercept - CORRECT ANSWER >>>The point where the graph crosses the
x-axis. Also known as the roots, solutions, or zeros in quadratics. ON THE X-
AXIS
y-intercept - CORRECT ANSWER >>>The point where the graph crosses the
y-axis. ON THE Y-AXIS
Maximum - CORRECT ANSWER >>>The highest y-value of the vertex.
Minimum - CORRECT ANSWER >>>The lowest y-value of the vertex.
Domain of a Linear, Quadratic and Exponential Function - CORRECT ANSWER
>>>All real numbers
Range of a Quadratic Function - CORRECT ANSWER >>>If open upward, y is
greater than or equal to the minimum value.
If open downward, y is less than or equal to the maximum value.
Point Slope Form of a Linear Function - CORRECT ANSWER >>>y - y1 = m(x -
x1)
Positive Slope - CORRECT ANSWER >>>The slope of a line going up to the
right
Negative Slope - CORRECT ANSWER >>>The slope of a line going down to
the right
