Mathematics
1 answer:
Lunna [17]3 years ago
3 0

Answer:

2nd option

Step-by-step explanation:

trinomial is 2x² + 10x -4 = 0

a = 2

b = 10

c = -4

(-b±√b²-4ac) / 2a

= [-10±√100-4(2)(-4)] / 2

= (-10±2\sqrt{33}) / 4

= (-5+\sqrt{33})/2, = (-5-\sqrt{33})/2  (simplified)

Y = 2x^2
GarryVolchara [31]

Answer:

y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)

Step-by-step explanation:

all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)

If a is positive then the parabola opens up,

the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises

the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis
