Vocabulary
The measurement of the angle of a straight line.
What is slope?
The slope-intercept form of a linear equation.
y = mx + b
In the equation y = 5*3x, the value of 3 is called this.
What is growth factor?
This is how you can tell that your coordinate is an x-intercept.
What is, when y = 0?
The percent that this equation is showing something increasing by.
y = 5000(1 + .05)5
What is 5%?
This is the graph of a quadratic function.
What is a parabola?
An equation of a line that has a slope of 3 and a y-intercept of -4
y = 3x - 4
When an exponential function is written in the form y = a(b)x, the initial amount is plugged in for this variable.
What is a?
This is where you look on a graph to find the solution(s) for a quadratic function.
What are the x-intercepts?
The place you look for on a graph to find the common solution for two linear equations.
What is the intersection point?
I am a word that represents the input, or x-variable, in a function.
What is the domain?
I am the standard form of a linear equation.
Ax + By = C
This is x4 * x6 written as a single exponent.
What is x10?
These are the solutions to (x + 5)(x - 7).
What are x = -5 and x = 7
(-5 + 5)(-5 - 7) = (0)(-12) = 0
(7 + 5)(7 - 7) = (12)(0) = 0
Solutions are the x-intercepts where y = 0.
The trinomial x2 +13x + 40 can be broken up into these binomial factors.
What is (x + 8)(x + 5)?
I am the type of function where you repeatedly add the same number over and over again, also known as constant change.
What is linear?
This is the x intercept of the equation 4x + 5y = 40
4(10) + 5(0) = 40
40 + 0 = 40
40 = 40
The number of bacteria you would have if you started with 100 bacteria and the number of bacteria triples each day can be written as this function.
What is y = 100(3)x?
This is the vertex of the equation y = 2(x - 4)2 - 7
What is (4, -7)?
The part in parentheses (minus = right, plus = left)
Integer at the end (plus = up, minus = down)
This is the solution to the following: f(3) = 2x + 5
What is 11?
f(3) = 2(3) + 5
I am what you use to show that the same number is repeatedly multiplied by itself.
What is an exponent?
This is how I can tell by looking only at the equations of two lines in slope-intercept form that the lines will be parallel.
Slope is the same.
This is (x5)3 written as a single exponent.
What is x15?
*Multiply the exponents when raising a power to a power.
This is (x +2)(x - 7) written as a trinomial.
What is x2 -5x - 14?
2 + (-7) = -5
2(-7) = -14
This is how you can tell that your coordinate is an y-intercept.
What is, when x = 0?
