The graph of the relation y = x2 + 2x + k passes through the point (2, 0). Find the values of k
Answer Details
We are given the equation y = x2 + 2x + k and we know that it passes through the point (2,0). We can substitute x = 2 and y = 0 into the equation to find k.
Substituting, we get:
0 = 22 + 2(2) + k
0 = 4 + 4 + k
0 = 8 + k
k = -8
Therefore, the value of k is -8, which is the fourth option.
