MATH110 2026 COMPREHENSIVE SET
SOLVED QUESTIONS AND SOLUTIONS
◉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. Answer: the magnitude of a real number without
regard to its sign.
How far a number is from zero.
◉difference quotient. Answer: The difference quotient is used to
calculate the slope of the secant line between two points on the
graph of a function, f
