The graph of the equations are straight lines except : [tex]y=x^2+3[/tex]
The graph of a quadratic function is called a parabola and has a curved shape. One of the main points of a parabola is its vertex. It is the highest or the lowest point on its graph.
According to the question
Graphs of the following equations :
A. 3x+2y=8
This is a straight line graph as it variables are linear and after plotting graph this can be seen .
Points
(0,4) (2,1) ....
B. y=[tex]\frac{x}{2}-5[/tex]
This is a straight line graph as it variables are linear and after plotting graph this can be seen .
Points
(0,-5) (2,-4) ....
C. x=4y
This is a straight line graph as it variables are linear and after plotting graph this can be seen .
Points
(0,0) (1,4) ....
D. [tex]y=x^2+3[/tex]
This is a quadratic equation , therefore its graph will be a parabola .By plotting graph can be observed.
Points
(-1,4)(0,3) (1,4)......
Hence, the graph of the equations are straight lines except : [tex]y=x^2+3[/tex]
