GRE Algebra | Graph of Functions

Graphs hold a very important place in the world of Algebra and are crucially components of GRE preparation. Graph functions are simple and must be understood carefully to successfully get correct answers in GRE. They are not difficult and once understood, will help in fetching marks easily.

Below are examples of some well known graphs of functions:

1. Linear fxn: Straight line graph where m is the slope and c represents the intercept in

y=mx+c

2. Square fxn: Shape of the graph is parabola.

y=x^2

3. Square Root fxn: Such graphs always lie in first quadrant.

y=x^1/2

4. Cube fxn 

y=x^3

5. Exponential fxn

y=e^x

6. Logarithmic fxn

y=ln(x)

7. Modulo fxn

y=|x|

8. Sine fxn

y=sin(x)

9. Cosine fxn

y=cos(x)

10. Tangent fxn

y=tan(x)
