You seem like a great teacher! Do you mind making a video/livestream for the NINTH grade shsat?
That's a great idea! One of my subscribers asked me to take an SHSAT cold on live stream, it was so much fun. I will add the 9th grade SHSAT to the queue!
thanks for the videos vin. im trying to check # 7 with my calc. but when i put y= 3x^2 -12 i get different values in my table....how do i fix this?
A common typo I have seen is that students will use the negative sign instead of the subtraction sign so the calculator multiplies by -12 instead of subtracting 12. Sometimes resetting the calculator can help.
Very informative video , trying to pass the ASVAB test . Do you think some of this problems are in the test as well ? Or similar
It looks difficult for me (
The last question is out of reach for the asvab as it requires the use of a graphing calculator. Some of the problems are fair game for the ASVAB; they have to be doable without a calculator.
is this test on algebra ll
This test is mostly focused on algebra 1, but there are definitely some useful techniques for an algebra 2 student. In algebra 2, you learn about focus/directrix, and complex numbers.
