Q:
# Rewrite the following quadratic function in vertex form. Then, determine the axis of symmetry. y=5x^2+15x-2

Accepted Solution

A:

5x^2+15x-2

5(x^2+3x)-2

5(x^2+3x+2.25-2.25)-2

5(x^2+3x+2.25)-13.25

5(x+1.5)^2-13.25

final answer: y=5(x+1.5)^2-13.25

axis of symmetry: (1.5, 13.25)

5(x^2+3x)-2

5(x^2+3x+2.25-2.25)-2

5(x^2+3x+2.25)-13.25

5(x+1.5)^2-13.25

final answer: y=5(x+1.5)^2-13.25

axis of symmetry: (1.5, 13.25)
