Remark
The key to this is the point (1,-3) That point must be found first. C is incorrect because you are using 3 not - 3 which does not change (as C has changed it) through out the problem.
A is using (-1,-3) which makes it wrong. Also the equation is y = -abs(x-1) - 3 which is also a mistake. The given graph points upwards not downwards.
D has it's min point at (-1,-3) which is not correct.
You are left with b which opens upwards (correct) has it's min at (1,-3) [also correct] so the answer is
Answer: B
Answer: 1/2+1/10=3/5
(8x4)-(7x3)= 11
Step-by-step explanation:
Answer: B
Step-by-step explanation: To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.
Answer:
shorter
Step-by-step explanation:
It's J. Honestly I just picked a number for X and a number for C and solved it using each answer. J works.
