Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = –3x2 – 36x – 60?
FromTheMoon [43]

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

Let f(x)=-3x-7 Abe g(x)=4x-5 find (f•g)(-3)
LiRa [457]

Answer:

272

Step-by-step explanation:

note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)

To evaluate substitute x = 3 into (3x - 7)(4x - 5)

(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172

How much coffee costing $4 a pound should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.3
Aleks04 [339]

Answer:

The quantity of coffee costing $4 a pound in the coffee mixture is 2 pounds.

Step-by-step explanation:

Given: Coffee costing $4 a pound is mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.30 a pound.

We have to find the quantity of coffee costing $4 a pound in the mixture.

Let x represent the number of pounds of $4 coffee.

Cost of one pound = 4x.

Cost of  3 pounds of coffee costing 4.50 a pound = 3(4.50)

Cost of mixture costing $4.30 a pound = (x+3)(4.30)

According to given problem,

4x+3(4.50)=(x+3)4.30

Solving for x, we get,

\Rightarrow 4x+13.5=4.30x+12.9

Rearranging like term together, we get,

\Rightarrow 13.5-12.9=4.30x-4x

\Rightarrow 0.6=0.30x

\Rightarrow x=2

Thus, the quantity of coffee costing $4 a pound in the coffee mixture is 2 pounds.
