Functions!
What IS a function?
A relation in which each input (x) has exactly one output (y)
Type Function you get when f(−x)=f(x)
What is an even function?
What is domain and range?
the set of input (x) values and the set of input (y) values
Other answers; Independent and dependent variables
Type function that goes f(−x)=−f(x)
What is an odd function?
A way to test if the graph lines are a function by testing if they intersect the graph no more than once
What is the vertical line test?
Determine if f(x) = 2x⁵ − 4x + 5 is even, odd, or neither
Neither
A function is ** if f(x1)=f(x2) for every x1 and x2 in the interval
What is a constant?
Given f(x) = x² + 1 and g(x) = 1/x, find (g ◦ f)(x)
1/(x² + 1)
For the function f(x)=−4x+2, this is the value of x when f(x) = 0
What is x=1/2?
For the relation {(-1,2), (0,4), (0, -3), (1, -3)}, these are the domain and range
What are Domain: {−1,0,1} and Range: {−3,2,4}?
