Answer:
0, $12.40, $24.79, $37.19, $49.58
0 ≤ f(g) ≤ 49.58
Step-by-step explanation:
The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)
So, f(0) = $0
f(5) = 2.479 × 5 = $12.40
f(10) = 2.479 × 10 = $24.79
f(15) = 2.479 × 15 = $37.19
and f(20) = 2.479 × 20 = $49.58
And the practical range of this function is 0 ≤ f(g) ≤ 49.58
Therefore, option D is correct. (Answer)
Hey There!! ☄️ The general vertex to The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.
Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.
From the choices we only have:
The graph of f(x) = x2 is made narrower
Answer:
x < 6
Step-by-step explanation:
5x < 30
5x/5 < 30/5
x < 6
Answer:
1. 1.28
2. 55
3. +
Step-by-step explanation:
1. 0.043 x 10 {3}
= 0.043 x (10 x 3)
= 0.043 x 30
= <u>1.28</u>
2. 5 + (9) (6) - 4
= 5 + 9 x 6 - 4
= 5 + 54 - 4
= 59 - 4
= <u>55</u>
