Answer:
C. G(x) has no root.
Step-by-step explanation:
A is wrong as the graph shows one minimum.
B is wrong as x approaches negative infinity, F(x) will approach infinity; not negative infinity.
D is wrong as it does not have 4 real roots.

Answer:

Step-by-step explanation:
we have

1500(0.04) = 60
60*3 or 60(3) = 180
Both equations are the same. I don't actually fully understand why you would use the same equation after the equal sign
