Practice Question & Answers
Average Rate of Change - Correct Answer Means SLOPE.
The "m" in front of x
Change in y divided by change in x
Exponential DECAY graphs - Correct Answer Exponential decay graphs curve down
Exponential GROWTH graph - Correct Answer Exponential growth graphs curve up
Midpoint formula - Correct Answer The point in the middle of a line segment
Parallel lines and slope - Correct Answer Have the same or equal slopes
Perpendicular lines & slope - Correct Answer Have opposite reciprocal slopes (flipped
and sign changed) Ex. 3/2--> -2/3
Domain of a relation - Correct Answer Domain: the x coordinates, input values,
independent variables, on x axis
Range of a relation - Correct Answer Range: the y coordinates, output values,
dependent variable, on the y axis
"adding or subtracting by the same amount" means... - Correct Answer The equation is
an LINEAR function
"multiplying by the same amount" means... - Correct Answer The equation is an
EXPONENTIAL function
Area formula for Rectangle - Correct Answer AREA= base * height or A= length * width
A=b*h or A= l*w
Diameter of circle - Correct Answer 2 radii = 1 diameter
radius = 1/2 diameter
No Solution vs. Infinitely Many Solutions (all real #'s) - Correct Answer When solving if
all variables disappear,
"No Solution": when 5=21
"Infinitely Many Solutions": when 5=5
Perimeter of figure - Correct Answer Perimeter = add up all sides of the figure
Volume of box or prism - Correct Answer Volume= L * W * H
, A cell phone company charges a $20 start up fee plus $0.10 per minute. Write a
function to model the situation. - Correct Answer y = 0.10 x + 20
Cost = 0.10 (# of minutes) + 20
To graph data on calc. - Correct Answer To enter data: STAT, edit, input#s, ENTER
To make scatterplot: turn on Plot 1, graph, ZOOM 9
Square - Correct Answer 4 equal sides
4 right angles
Rectangle - Correct Answer opposite sides equal
4 right angles
Normal Distribution - Correct Answer Mound of data in the middle
High in the middle, even on each side
Standard Deviation (what does it mean?) - Correct Answer 2/3 of data or 67% of data is
under the mountain
Positively Skewed - Correct Answer long tail on the right
Negatively Skewed - Correct Answer long tail on the left
Translations-vertical shifts - Correct Answer adding positive # on the end moves graph
up
adding negative number moves graph down
Translations - horizontal shift - Correct Answer adding a positive # inside ( ) to the x,
moves graph to the right or left
Line of best fit - Correct Answer Also called "regression line", "linear model", "prediction
equation", or "trend line".
Use calculator to find
STAT, edit, input L1 and L2,
Stat, -> CALC,
#4 LinReg
Pythagorean Theorem - Correct Answer Only use for Right Triangles
* c is the hypotenuse
Exponent rule for power raised to a power
(1 base with 2 powers) - Correct Answer Power is outside a parenthesis
Distance Formula - Correct Answer
