Answer 2

To plot the graph of the equation y = 0.4x^2, we can start by creating a table of x and y values:

Let's choose some x values and substitute them into the equation to find the corresponding y values:

-2: y = 0.4(-2)^2 y = 0.4(4) y = 1.6

-1: y = 0.4(-1)^2 y = 0.4(1) y = 0.4

0: y = 0.4(0)^2 y = 0.4(0) y = 0

1: y = 0.4(1)^2 y = 0.4(1) y = 0.4

2: y = 0.4(2)^2 y = 0.4(4) y = 1.6

Now we can plot these points on a graph:

(-2, 1.6), (-1, 0.4), (0, 0), (1, 0.4), (2, 1.6)

Next, we can draw a smooth curve connecting these points. Since the equation is a quadratic function, the graph will be a symmetric U-shape.

Note that the coefficient 0.4 determines the steepness of the curve. The larger the coefficient, the steeper the curve. Similarly, a negative coefficient would cause the graph to be upside down.

Here is a visual representation of the graph of y = 0.4x^2:

   2 ┤      .   
     ┤       .   
 1.5 ┤        ..
     ┤         ..
   1 ┤          ..
     ┤           ..
 0.5 ┤            ..
     ┤            ..
   0 ┼-------------.------------
     -2  -1   0   1   2

As you can see, the graph is symmetric with respect to the y-axis and touches the x-axis at the origin (0,0). Its shape resembles an "U".

I hope this helps! Let me know if you have any further questions.
