Which equation would include all of these points?
(-2,3), (-1,-3), (0, -5), (1, -3), (2, 3), (3, 13)

A)y = 2x + 5
B)y = 2x-5
C)y= 2x² + 5
D)y = 2x(2) - 5

Answer:

D. [tex]y = 2\cdot x^{2}-5[/tex]

Step-by-step explanation:

The given points show a symmetry that corresponds with a second-order polynomial (a parabola), that is:

[tex]y = A\cdot x^{2}+B\cdot x + C[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A, B, C[/tex] - Coefficients.

Since the absolute minimum is associated with [tex]x = 0[/tex], then we infer the following conditions:

[tex]A > 0[/tex], [tex]B = 0[/tex], [tex]C = -5[/tex]

Therefore, the correct answer is D.
