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.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
