What can be said about the discriminant of the graph below?

C. The discriminant is negative, so there are no solutions.

Step-by-step explanation:

We see that the given figure is a graph of a parabola.

The equation of the given parabola is .

Simplifying the equation in quadratic form, we get,

The equation is i.e. i.e. .

We know that the discriminant of a quadratic equation is given by

So, from the equation , we have,

a = 1, b = -6 and c = 10

Thus, the discriminant is

i.e.

i.e.

So, the discriminant is -4 i.e. negative.

Hence, as the discriminant is negative, there are no solutions.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
