Quadratic graphs worksheet

Quadratic Polynomial is of the Form $ax^2 + bx+c$. Geometrically it is represented by the Parabola on the Graph. The zeroes or the root of the quadratic are the point on x-axis where it intersect the x-axis. Here in this post of Quadratic graphs worksheet , we have asked upon few questions based on these concept only. I hope this is help in your preparation

c.

3.

Match the column

Quadratic graphs match the column

4. Draw the Graph of the below quadratics

(a) $x^2 -7x +10$
(b) $x^2 +x -2$
(c) $x^2-9x+20$

5. Which of the follow does not have real roots

Which of the follow quadratic graphs does not have real roots

Answer

1.

Zeros of quadratic polynomials are the points at which it intersect x axis. Based on this , the answers are

a. -1,3

b, -1,0

c. 2,4

2.

a. $x^2 + 3x  -4$

b.$ -x^2 -x +6$

c. $ -x^2 +4x -4$

3.

we can easily do this by find the zeros of the quadratic equation and then matching with the graph

4.

5. For real roots, the graph should intersect the x axis . Here graph (a) and (c) does not intersect the x-axis, so those quadratic polynomials does not have any real roots
