F(x)=-4x^2+10x-8

vazorg [7]

Answer:

Step-by-step explanation:

a = - 4

b = 10

c = - 8

The discriminate is

D = b^2 - 4ac

D = 10^2 - 4*(-4)(-8)

D = 100 - 128

D = - 28 which is not a nice number

Because the Discriminate has a minus result, there are no real zeros.

What is the vintercept of the line whose equation is y= 1/2x-3

klemol [59]

Answer:

The y-intercept of line is (-3)

Step-by-step explanation:

Given equation of line is given by y= $\frac{1}{2}x-3$

The general equation of line is given y=mx+c

Where, m= slope of line

c= y-intercept of line

On comparing both the equation.

c=(-3)

y-intercept is when x=0,

therefore,

y= $\frac{1}{2}x-3$

y= $\frac{1}{2}(0)-3$

y=(-3)

Thus, y-intercept of line is (-3)
