Quadratics Exponential functions Equations and Inequalities Functions Exponent Rules
The maximum ( highest) or minimum (lowest) point of a parabola.
What is vertex of a graph?
Growth & Decay.
What are the 2 types of exponential functions?
> or ≥
What symbol means to shade above ?
The x-intercept.
What is the zero of a function?
5^4
Which is equivalent to 5 x 5 x 5 x 5?
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 ?
Yes, it passes the vertical line test.
Is y=4 a function ? Why or why not?
1
Anything raised to a power of zero is always:
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 ?
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
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.
How can you tell if a equation is a function on a table?
2¹⁶
Simplify the following:
(2⁸)²
