A is a function because you have a different value for x.
B is not a function because you can't have the x value have a number twice, in this case it's 2.
C is not a function for the same reason as B.
D is a function because there is always a different x value.

PLEASE HELP ASAP WILL MARK BRAINLIEST<br><br> Solve the quadratic equation <br> 18x^2 -153x -172 =0
Vika [28.1K]

Answer:

The answer is : x = 9.505 and x = -1.005

Step-by-step explanation:

To solve the quadratic equation use the formula :

x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}

Where a is the coefficient of x² , b is the coefficient of x and c is the numerical term

∵ a = 18 , b = -153 and c = -172

∴ x=\frac{-(-153)+\sqrt{(-153)^{2}-4(18)(-172) } }{2(18)}

x = \frac{18+\sqrt{35793} }{36} &x=\frac{18-\sqrt{35793} }{36}

∴ x = 9.505 and x = -1.005
