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!

May SAT Scores are in!
Originally inspired by this Spring 2009 Wall Street Journal article whose author was dared by her teenage son to take the SAT, I took the SAT in 2009 and got 2 Math questions wrong scoring a 750. Last month, I took the new SAT and made no errors on Math :)
And just as I thought the Reading was harder — well at least it was for me as compared to 2009! Khan Academy was wonderful as was the College Board book.
I highly recommend for adults to take this exam — I learned a lot of content prepping and had intense focus for 5 hours!! Plus it builds rapport and connection with teens!
Scroll to the bottom of this College Board policy for dates that adult test takers can sit.

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

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!!!
