Question

Complete the table of values for y = x2 - 4x

Answer 1

Answer:

-1      0      1      2      3      4      5

5      0     -3     -4     -3     0      5

Curve (B) best matches the given graph.

Step-by-step explanation:

When given the following function,

$y=x^2-4x$

The problem asks one to evaluate the function for the given list of values, substitute in each of the values and solve to find the value of (y),

(-1)

$y=x^2-4x\\y=(-1)^2-4(-1)\\y=1+4\\y=5$

(1)

$y=x^2-4x\\=(1)^2-4(1)\\=1-4\\=-3$

(2)

$y=x^2-4x\\=(2)^2-4(2)\\=4-8\\=-4$

(4)

$y=x^2-4x\\=(4)^2-4(4)\\=16-16\\=0$
