Given:
We are given ordered pairs of values for g(x) whose x-values are
-7, -2.5, 0, 0.5, 4, and 9.
After reflection across the x-axis, f(x) should have negative x-values, but the same y-values.
Use the calculator to create a table of f(x), with x-values of
7, 2.5, 0, -0.5, -4, and -9.
x: 7 2.5 0 -0.5 -4 -9
f(x): -10.206 -1.025 -0.286 -0.221 -0.037 -0.003
The corresponding values for g(x) will match f(x), but the x-values will be multiplied by -1.
Answer:
Of the given answers, only these are correct:
(-7, -10.206)
(0.5, -0.221)
(9, 0.003)
