Answer:
In interval notation it is ( -∞, ∞).
Step-by-step explanation:
All values of x can be input to this function.
8 x 6 = 42 add two zeros so 4200
Answer:
There are two ways you can write it. You can write it how you would casually say it:
Fifty and two (or Fifty point Two)
But mathematically, you would say it as:
Fifty and Two-tenths.

Answer:
Step-by-step explanation:
You'll need to find a way to share the graph or graphs associated with this problem.
The period is 4. The relationship between period and b (the coefficient of the independent variable of the cosine function) is (period) =(2π.b). Given that the period here is 4,
2π 2π
4 = ---------, and so b = ------- = π/2.
4
So now our y = a*cos (bx + c) becomes
π
y = 10*cos (------x + 0 + 10
2
The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.
