# Get the Math and the Points June 2015 CC Alg I #4 A function has to have unique x values.
Look at
(1) 2 and 4 repeat repeat
(2) 0 repeats
(3) all unique
(4) 0 repeats

That’s it — 2 more points!

# Get the Math and Points Jan 2015 CC Alg I Regents #5 Linear means every time x goes up by the same amount (in this case, 1), y goes up by the same amount each time.
So we need to look at the f(x) column of each answer and see if there is a consistent rate of change.
Answer 1: not going up by the same rate
Answer 2:  definitely a pattern but not going up by the same rate
Answer 3: each f(x) value is 2 more than the one above it 🙂
Answer 4: not going up by the same rate

# Get the Math and Points Jan 2015 CC Alg I Regents #4 This is purely a reading problem!
How many years from when Krystal was 2 til she’s 18?
That number is the exponent leaving answer choice (1) and (2)
Then we have to ask ourselves is the account increasing or decreasing and that leads us right to the right answer!!
That’s it — 2 points!!!

# Get the Math and Points CC Alg I Regents Aug 2014 #22 The left part of the graph is parabolic as it looks curvy and we know this for sure as all of the f(x) or y = x^2 is the same for the top part of each answer choice when x<1.
We need to analyze the linear part of the function.   Below please find the line extended.
Since the equation of a line is y = mx + b where m is slope and b is y-intercept, we can find b by looking at the line below.
It crosses the y-axis at 1/2 so look at the answer choices and find the equation with a b of 1/2.
That’s it!! 2 points 🙂 # Get the Math and the Points Aug 2014 #35   At x = -2, both y values are 8 and at x = 1 both y values are -2.
This can also be seen on the graph…That’s it — 4 points!!
