|
|
X-intercepts, where the line intersects the x-axis.
What are roots?
|
A line that a graph approaches but never intersects.
What is Asymptote?
|
< or ≤
What symbol means to shade below ?

|
|
Vertical line that goes through the vertex and divides the parabola in 2 symmetrical parts.
What is the axis of symmetry ?
|
y= a(b)^x
What is the equation for exponential functions?
|
Make sure it’s in slope intercept form and start with the y- intercept.
What is the first step to graph a inequality or equation?
|
No, doesn’t pass the vertical line test.
Is x=-2 a function? Why or why not ?
|
add
According to exponent rules, when we multiply the same base we _______ the exponents.
|
|
Minimum value is -8.
What is the maximum/minimum value if the vertex is (-2,-8)?
|
3
Identify the initial value: y= 3(1.8)^x
|
Double shaded area.
In what area of 2 graphed inequalities are the solutions?
|
Use the vertical line test.
How can you tell if a equation is a function on a graph?
|
multiply
According to exponent rules, when we raise a power to another power we _______ the exponents.
|
|
ax^2+bx+c
What is the equation for quadratic functions?
|
Decay.
Tell wether it’s growth or decay : y= 0.5^x
|
y≥ 1/3x-3
Solve the inequality for y: x-3y≤9
|
If the x’s repeat it is not a function , if they don’t repeat it is a function.
