Answer:
third one is not true means wrong
TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
Answer
v=-35
explanation
add -4 and -31 to get v which is -35
3/9 + 1/2 = 5/6
2 1/3 + 2 1/4 = 4 and 7/12
