Answer:
See explanations below
Explanation:
Gien the functions
f(x) = 2x^2 - 1
g(x) x - 5
when x = 0
f(0) = 2(0)^2 - 1
f(0) = 0 -1
f(0) = -1
when x = -2
f(-2) = 2(-2)^2 - 1
f(-2) = 2(4) - 1
f(2) = 8 - 1
f(2) = 7
when x = 5
f(5) = 2(5)^2 - 1
f(5) = 2(25) - 1
f(5) = 50 - 1
f(5) = 49
For the function g(x)
when x = -5
g(-5) = -5 - 5
g(-5) = -10
when x = 0
g(0) = 0 - 5
g(0) = -5
when x = 5
g(5) = 5 - 5
g(5) = 0
