They intercept in two points.
The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)
The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..

If you know how the two graphs look like then you can understand why they intercept only two times.
The end behavior of functions with exponents is quite simple when you realized that as x approaches infinity that the function will act as if the highest exponent term is the only one which exists...
In this case 3x^8 is the highest order term, so y approaches +oo as x approaches +oo or -oo. Or in other words y increases without bound as x approaches ±oo
Answer:
Yes
Step-by-step explanation:
If (4,11) is part of the system, it should satisfy both equations
y = 4x - 5
11 = 4(4) - 5
11 = 16 - 5
11 = 11 is a true statement
y = 2x + 3
11 = 2(4) + 3
11 = 8 + 3
11 = 11 is a true statement
Since (4,11) satisfies both the equations, it is part of the system
Answer:
The first option
Step-by-step explanation:

Answer:
r = - 189
Step-by-step explanation:
Given
- 13 =
+ 8 ( subtract 8 from both sides )
- 21 =
( multiply both sides by 9 )
- 189 = r
