QUESTIONS AND CORRECT ANSWERS
GRADED A+
⩥ x-intercept.
Answer: the x-coordinate of a point where a line, curve, or surface
intersects the x-axis.
⩥ Slope of a line.
Answer: The slope of a line (also called the gradient of a line) is a
number that describes how "steep" it is.
the slope or gradient of a line is a number that describes both the
direction and the steepness of the line.
⩥ point-slope form.
Answer: the equation of a straight line in the form y − y1 = m(x − x1)
where m is the slope of the line and (x1, y1) are the coordinates of a
given point on the line — compare slope-intercept form.
⩥ linear equations.
Answer: an equation between two variables that gives a straight line
when plotted on a graph.
, ⩥ square function.
Answer: square map is a function defined on all real numbers that sends
any real number to its square, i.e., its product with itself
⩥ Interpolation.
Answer: Interpolation is an estimation of a value within two known
values in a sequence of values.
⩥ Extrapolation.
Answer: an estimation of a value based on extending a known sequence
of values or facts beyond the area that is certainly known
⩥ Range and Domain.
Answer: The domain is the set of all possible x-values which will make
the function "work", and will output real y-values.
The range is the resulting y-values we get after substituting all the
possible x-values.
⩥ Vertical shift.
Answer: A vertical shift is when the graph literally moves vertically, up
or down. When a function shifts vertically, the y-value changes.
⩥ Absolute Value.
