Describe the graph of the function.
gayaneshka [121]

Answer:

The answer is option 1.

Step-by-step explanation:

Axis of symmetry means the middle x-coordinates of the parabola. So in order to find the x value, you have to find the TP which is Turning Point by using Completing the Square :

{(x +  \frac{b}{2} )}^{2}  -  {( \frac{b}{2} )}^{2}  + c = 0

Let y = 0,

2{x}^{2}  + 12x - 15 = 0

2( {x}^{2}  + 6x -  \frac{15}{2} ) = 0

{( {x +  \frac{6}{2}) }^{2}  - ( { \frac{6}{2} )}^{2}  -  \frac{15}{2} } = 0

( {x + 3)}^{2}  -  {(3)}^{2}  -  \frac{15}{2}  = 0

( {x + 3)}^{2}  - 9 -  \frac{15}{2}  = 0

(x { + 3)}^{2}  -   \frac{33}{2}   = 0

2(x { + 3)}^{2}  - 33 = 0

Next, you have to solve the x value :

x + 3 = 0

x = -3
