The numbers that complete the table of values for y = x² + 4x - 3 are:
A = -6
B = -3
C = 2
How to complete the table of values?
The quadratic equation is given as:
y = x² + 4x - 3
The table of values is given as:
x | -3 -2 -1 0 1
y | A -7 -6 B C
Substitute the value of x into the equation
A:
When x = -3
y = x² + 4x - 3
y = (-3)² + 4(-3) - 3
= 9 - 12 - 3
= -6
B:
when x = 0
y = x² + 4x - 3
= (0)² + 4(0) - 3
= 0 + 0 - 3
= -3
C:
when x = 1
y = x² + 4x - 3
= (1)² + 4(1) - 3
= 1 + 4 - 3
= 2
Therefore, A = -6, B = -3 and C = 2 respectively.
Complete question is:
Copy and complete the table of values for y = x² + 4x - 3 What numbers replace A, B and C?
x | -3 -2 -1 0 1
y | A -7 -6 B C
