Question

Which statements are true, if f(x) = x2 and g(x) = –x? Check all that apply. For any value of x, f(x) > g(x). For any value of x, f(x) < g(x). When x = –3, f(x) < g(x). When x = 2, f(x) > g(x). For all positive values of x, f(x) > g(x). For all negative values of x, f(x) > g(x).

Answer 1

yeah
as f >g alwys not true
as for x= -1/2
f<g

Answer 2

for x= 1 f>g
so f<g not alwys true

Answer 3

at x=-3
f=(-3)^2=9
g=-(-3)=3
f>g not less than g

Answer 4

at x=2
f=4
g=-2
so f>g

Answer 5

For all positive values of x, f(x) > g(x).true as we seen above
For all negative values of x, f(x) > g(x ) false

for example x=-1/2
f=1/4
g=1/2
g>f
