Answer:
2. False
3. False
Step-by-step explanation:
Solving inequalities requires the same steps as solving equations except for one exception. When you multiply or divide by a negative during the solving process, you must flip the sign to maintain the relationship. This occurs when the variable x has a negative coefficient. Neither 2 nor 3 has this case. Neither needs the sign flipped. Both are false.
5p-9=2p-12
5p-2p=-12+9
3p=-3
p=1
Well the first obvious thing is that the axis of symmetry is 0.5, so we can automatically cross out (C).
All the answers have the correct vertex, so lets find the formula for the function.
Fortunately, from my point of view, I can see two points that have their coordinates as integers, (-1, -3) and (2, 3), we can plug these into the already given "formulas" in the options (A), (B), and (D).
Out of the three choices, the formula in option (D) satisfies both coordinates, thus option (D) is correct.
