Question

Complete the table of values for y=x^2-4x+3

Answer 1

• y=x²-4x+3

x=1

• y=1²-4(1)+3=1-4+3=0

x=2

• y=2²-4(2)+3=4-8+3=7-8=-1

x=3

• y=3²-4(3)+3=9-12+3=12-12=0

Answer 2

The equivalent values to complete the table are 5, -1, -4 and 0
Given the function according to the table shown:

When x = -1

When x = 1

When x = 2

when x = 4

Hence the equivalent values to complete the table are 5, -1, -4 and 0
