A shark's depth in meters relative to sea level over time in minutes, x, is modeled as a parabola. At time 1 minute the shark is swimming upwards and is at a depth of 7 meters. The shark continues to swim toward the surface for another minute and then turns and begins to swim downwards and returns to a depth of 7 meters at time 3 minutes. What is the axis of symmetry of the graph of the parabola?

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
