Exit Ticket: Use finite differences to determine whether each of the
tables below represent a linear or quadratic function. If linear
determine whether the function is increasing or decreasing. If
quadratic, determine whether the functions opens upward or
downward

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

answer:

c) the x-coordinate of the center of the circle increases by 3

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
