The graph of a quadratic function y = ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive negative, or zero.

The discriminant is equal to 0.

Step-by-step explanation:

The graph shows the parabola with branches go down in negative y-direction. This gives you that a<0.

Since parabola has one x-intercept, then the equation has two equal solutions and the discriminant is equal to 0.

Zero

Step-by-step explanation:

1. By definition: if the discriminant is negative, the quadratic equation does not have real solutions, it has two imaginary solutions. If the discriminant is zero the quadratic has one solution. If the discriminant is positive, the quadratic equation has two distinct solutions.

2. You can see that the function touches the x-axis, this only happen when the solution of the function is even . Then, the function has only one solution. The discriminant is zero.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
