Describe the graph of the function. y = 9x^2 + 18x – 6 1.) the graph is a parabola with axis of symmetry at x = 1. 2.)the graph is a parabola with axis of symmetry at x = 9. 3.)the graph is a parabola with axis of symmetry at x = 6. 4.)the graph is a parabola with axis of symmetry at x = –1.

Option 4 is correct.

Step-by-step explanation:

Given:  function , y = 9x² + 18x – 61

y = 9x² + 18x – 61

Take 9 common from each term of RHS

using complete the square method on RHS we get,

⇒ Equation of Parabola is 9 (x+1)² = y + 70

Line of Symmetry is x = -1

Therefore, Option 4 is correct.

answer: 800

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
