Starts at 20 so look for y-intercept of 20
Leaves answers (2), (3) and (4)
Doubles every 10 years so must go up.
Leaves answers (3) and (4)
Which one looks like doubling every 10 years
(0, 20) is the starting point
(10,40) ten years and it doubles
(20,80) ten more years and it doubles again
(30, 160) ten more years and it doubles again
(40, 320) ten more years and it doubles again
Now we are off the graph!!
Look at the graph above to the right, where does it cross the x-axis?
Confirm these values by looking at the table below…for what x values does y = 0?
Find those values in one of the answer choices above. TWO POINTS!!!
By putting the original algebra into Y1 and answer (1) into Y2, we can see that the tables are exactly the same which means equivalence!!
(if they were not the same, we would change Y2 to be the next answer and compare those y values with Y1)
Um, so this graph looks like which graph above??
Match it pick it — 2 more points!!!
The new CC Algebra II Regents was given yesterday Wednesday June 1, 2016.
It has not yet been released to the wider world but word has it:
New York is extremely ambitious on the Math they think students can learn, the Math teachers can teach and the support parents and siblings can provide. It will be about 3 more weeks until scores are able to be assigned after the state releases the scaled score.
Here are the Sample Items released by NY last Fall: 2015SampleItemsAII
Til then best wishes to all students taking the Algebra 2 Trig Regents on June 17 and to all students on their finals and Regents!!
