Question

f(x) = x + 6 , find the ordered pair when x = -2.

(-2,4)

(2,-4)

(-2,-4)

(2,4)

Answer 1

-------------------------------------------------------------------------------------------------------------

Answer:  $\textsf{Option A, (-2, 4)}$

-------------------------------------------------------------------------------------------------------------

Given:  $\textsf{f(x) = x + 6}$

Find:  $\textsf{f(-2)}$

Solution:  We need to plug in the value -2 into every variable x that we have in the expression and simplify to get the solution.

Plug in the values

• $\textsf{f(x) = x + 6}$

• $\textsf{f(-2) = -2 + 6}$

Simplify

• $\textsf{f(-2) = -2 + 6}$

• $\textsf{f(-2) = 4}$

Therefore, the ordered pair that would match would have a x-coordinate of -2 and a y-coordinate of 4 producing (-2, 4) which matches option A.
