Question

Using expressions with the given x^(2)-3x-9 when x=-4

Answer 1

When x = -4, the value of x^2 - 3x - 9 is 19.

Step-by-step explanation:

When substituting x = -4 into the given expression x2 - 3x - 9, we can evaluate it as follows:

x2 - 3x - 9 = (-4)2 - 3(-4) - 9 = 16 + 12 - 9 = 19.

Therefore, when x = -4, the value of the expression x2 - 3x - 9 is 19.
