What are the solutions of the equation x4 + 3x2 + 2 = 0? Use u substitution to solve. X= tin2 and x = +1
Ox=tiv 2 and x = +
X=12 and x = ti
Ox=1V and x = +1

x=6 and x=3

the graph is negative for all real values of x where   -6 < x < -2.

step-by-step explanation:

this refers to the values of f(x) in the area below the x-axis.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
