Answer:
6. a) The coordinate of the y-intercept is (0, 4)
b) The y-intercept represent the initial distance before she started hiking
7. The domain of the function is 0 ≤ c ≤ ∞
8. The correct option is;
b. all real numbers from 2.6 to 13"
9. Please find attached the required graph of the function created with Microsoft Excel
Step-by-step explanation:
6. From the given graph, we have;
The coordinate of the y-intercept = (0, 4)
The y-intercept represent the initial distance before she started hiking
7. The given function that models the number of cans Luis will have after his purchase is f(c) = 24·c + 5
The domain of the function is the possible values of "c", which is 0 ≤ c ≤ ∞
∴ The domain of the function = 0 ≤ c ≤ ∞
8. The number of hours Roger plays video games, t is 2 ≤ t ≤ 5
The number of games Roger plays on average within an hour = 2.6 games
The function f(t) = 2.6·t gives the number of games Roger plays in "t" hours
Therefore, we have;
The range = f(2) ≤ f(t) ≤ f(5) = 2.6 × 2 ≤ f(t) ≤ 2.6 × 5 = 5.2 ≤ f(t) ≤ 13
The range of the function = 5.2 ≤ f(t) ≤ 13
The correct option is "b" " all real numbers from 2.6 to 13"
9. Please find the required graph of the function , created with Microsoft Excel.

Answer:
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
where (h,k) is the vertex of the parabola
The axis of symmetry is equal to
In this problem the parabola open upward
so
the coefficient a is positive
The coordinates of the vertex will be (the y-coordinate is negative)
so
the equation will be of the form
