Answer 1

function

Question 2

each element of the range corresponds to an element of the domain

Answer 2

onto function

Question 3

each element of the domain pairs to exactly one unique element of the range, and each element in the range corresponds to a unique element of the domain

Answer 3

both one to one and onto

Question 4

Answer 4

discrete relation

Question 5

the domain of a relation having an infinite number of elements and the relation can be graphed as a line or smooth curve

Answer 5

continuous relation

Question 6

the variable, usually x, with values making up the domain is called this

Answer 6

ratio that compares how much one quantity changes, on average, relative to the change in another quantity

Answer 14

rate of change

Question 15

ratio of the change in the y coordinates to the corresponding change in the x coordinates

Answer 15

slope

Question 16

y=mx+b

Answer 16

slope-intercept form

Question 17
