Need with the third table at the top of the page, not sure what kind of function it represents.

Table 1: Linear function. For each time x increments by 1, y increments by 2. y=2x.

Table 2: Exponential function. Each time x increments by 1, y divides itself by 4.
y= 0.25^x

Table 3: Quadratic function. Notice how the y values seem to increase by less and less before coming back down in an opposite fashion. This is characteristic of a parabola.

Hi there! The answer is x = 6


First get rid of the parentheses (by multiplying)




Then collect the terms


Next, we add 51 to both sides of the equation.


Finally divide both sides of the equation by 12.


Therefore, the answer is x = 6
