Which graph is a parabola? On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It is asymptotic to the negative x axis and crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, 1).

On a coordinate plane, a curved line opens up and down in quadrants 1 and 3. It crosses the x-axis at (negative 1, 0), turns to the right, crosses the y-axis at (0, 1), then turns up sharply.
On a coordinate plane, a parabola opens up. It goes through (negative 2.2, 10), has a vertex of (0.25, negative 1), and goes through (2.6, 10).

On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It goes through (negative 3.3, 10), crosses the y-axis at (0, 1), and is asymptotic to the positive x-axis.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
