solve for n
1/7m + 1/4n = 24
n = 96 - 4/7m
what is the definition of functions
a relationship or expression involving one or more variables.
what is the formula for point slope form ?
y- y1=m(x-x1)
what is the formula for a quadratic equation
ax2+bx+c=0
what is the definition of an exponential function.
definition of literal equations
A literal equation is an equation which consists primarily of letters. Formulas are an example of literal equations.
is the graph a function if a horizontal line passes through it twice? why or why not .
it is not because you can not have 2 x points on the same line.
y-10=-3(x-2)
y=-3x+16
what is the graph of a quadratic function called
the graph of a quadratic function is called a parabola.
what is an asymptote?
a line that continually approaches a given curve but does not meet it at any finite distance.
solve 6x-3y=12
y=2x-4
how do you determine if a table is a function .
when there aren't 2 of the same numbers in the x input .
write a linear equation that has a slope of -3 and goes through the point (2,4) .
1 y-4=-3(x-2)
what does it mean if the vertex on a parabola is a maximum .
it means that the vertex is at its highest point.
what is the formula used for an exponential function.
f(x) = bx
7x-y = 12
y=12+7x
D because there are two threes in the x slot .
write an equation in point slope form that passes through the the given slope and given point
slope of -2 and point (-3,5)
.
y-5=-2(x+3)
how can you determine if an equation is a quadratic equation or not .
every quadratic equation has to have an x2 if x2 is not present then the equation can not be put into the calculator .
what does the a variable in an exponential formula stand for .
the base
5y=15
y=3
is this graph considered a function
yes because a horizontal line would only hit once .
in this formula y-y1=m(x-x1) which number or variable represents the slope.
the m represents the slope
name 3 transitions in quadratic equations and what they do.
flip
steep
flat
what are the 3 keys to exponential functions
1. y- intercept
2.horizontal asymptote
3.growth and decay
