Any help will be appreciated

Answer:
9. -1, 2
10. 23, -142
11. 7, -14
Step-by-step explanation:
So for each you take the number in parentheses and plug in x = 0 into the equation:
[tex]f(0) = 2x - 1\\f(0) = 2 * 0 - 1\\f(0) = -1[/tex]
[tex]g(0) = 2 - x^2\\g(0) = 2 - 0^2\\g(0) = 2[/tex]
I'll do a couple more but there's too many for me to answer all of them.
