Answer:
B
Step-by-step explanation:
(a) Complete the table by substituting the values of x into y = x² - 4x
x | - 1 0 1 2 3 4 5
y | 5 0 - 3 - 4 - 3 0 5
Considering ordered pairs from the table
(0, 0 )
The only graph that passes through the origin is graph B
Graph B also goes through all the given points in the table

20, represents the full base. but the rectangle’s base is 10. both triangles are equal so 20-10 equals 10 and split them evenly on both sides.
6•5=30/2=15
since you have two equal triangles your total answer is 30. then you do 10•7 which is 70.
That is because there are many quadratic functions that have the same axis of symmetry. If a function is multiplied by a constant factor the axis of symmetry remains the same but the curved part of the graph widens or narrows.
For example x^2 + x - 6 and 2x^2 + 2x - 12 The last function will have same axis of symmetry and same roots as the first but the curved part will be narrower.
Also if we multiply the first function by -1 the curve will flip about the x axis but will have the same axis of symmetry

The one in the thousands is 100 times greater than the one in the tens
Hope this helps!
