Since ax2 2bxc.

. Consider the following statement. Multiple Choice If b2 - 4ac 0 which conclusion can made about the graph of fx a The graph has two distinctx-intercepts. If a 0 and b 0 then the equation is linear not quadratic as there is no term The numbers a b and.

Where x represents an unknown and a b and c represent known numbers where a 0. The discriminant is b2 - 4ac which comes from the quadratic formula and we can use this to find the nature of the roots. Therefore the graph of y a x 2 b x c intersects the x axis at only one point.

Free JEE Main Mock Test. B2 ac 1 b 2 - a c 1. Roots can occur in a parabola in 3 different ways as shown in.

If b2 - 4ac 0 and a 0 then the graph of y ax2 bx c has two x-intercepts. Solve Study Textbooks Guides. PM ANSWERED BY EXPERT.

B The graph has no x-intercepts. If a 0 and b 2 4 a c 0 then. True False b If it is.

A Determine whether the statement is true or false. The discriminant of the quadratic equation is the part that is below the square root of the quadratic formula. Click hereto get an answer to your question If a 0 and b2 - 4ac0 then the graph of y ax2 bx c.

Solve Study Textbooks Guides. Looking at the graph we clearly see that there is 2 cutting. The square root of the discriminant is the distance between the zeros in case we have a 1.

Since b 2 4 a c 0 hence 4 a c b 2 0 Also x 2 a b 2 0 perfect square. In some books the discriminant is represented by the greek letter Δ. By looking at the value of the discriminant in a quadratic we can find the nature of roots.

If a 0 graph of the curve will be concave upwards. This is the form of a hyperbola. The value of k for which x-2is afoot of a square of a quadratic equation kx square x-60 Asked by ashleshathakur124 20 Oct 2019 0602.

B2 4ac 0 b 2 - 4 a c 0. We have x12 2ab b24ac. Class 12 Chapterwise MCQ Test.

Use this form to. Since b 2 4 a c 0 Hence there is single equal roots root to the above equation. If b 2 4 a c 0 then the graph of y a.

The roots are equal. Click hereto get an answer to your question If b2 - 4ac 0 then the graph of y ax2 bx c. Solution for If a0 and b2-4ac0 determine the possible corresponding graph of fxax2bxc.

You cant take the square root of a negative number so this means there are no real roots and the quadratic doesnt cross the x axis. Hence A is the correct option. Free NEET Mock Test.

And for b 2 4 a c 0 graph of the curve will not touch the x-axis at any points. Hence whether y is greater than or lesser than zero is dependent on the value of a. Look at the formula.

Since it is given that a 0. In your plot we have 71 6 36 Δ. Tap for more steps.
