Ответ:
We can do this by doing 40 divided by 100 which gives us: 0.40
Therefore 40% in decimal form is 0.40.
Next we do 80 x 0.40 which gives us 32, this means Justin has already made 32 illustrations.
Next we do 80 - 32 which gives us 48, this means Justin still has to do 48 illustrations.
I hope this helps!

Step-by-step explanation:
A second order polynomial (quadratic function) can be well represented with at least three distinct points. Let is take five equidistant different points:
x = 0
x = 1
x = 2
x = 3
x = 4
The table of points from the equation
is:
0 2
1 -3
2 -2
3 5
4 18
