Describe the graph of the function. y = 2x2 + 12x – 15

Step-by-step explanation:

To describe the graph of the function y=.

The function y= is a quadratic function. All quadratic function have a parabolic curve. The direction to which the parabola opens is determined by the coefficient of , If the coefficient of , is positive as in the case above, the graph forms a downward "U" shape.

The solutions of the function y= are 1.06 and -7,06, This means the graph intersects the x-axis at points 1.06 and -7.06.

To determine the axis of symmetry of a downward facing parabola,

We use the equation:

a=2, b=12.

Axis of Symmetry=

The minimum point is the value of y at the axis of symmetry.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
