Y=4 Because you divide 18 by 4.50 and then just put a point on positive four on your graph.

We are given x represent the number of pencils purchased, and let y represent the total cost.

We also given 18 pencils for $4.50.

Therefore, cost of each pencil = 4.50/18 = $0.25

Total cost (y) = cost of each pencil × number of pencils.

Therefore, equation would be

<h3>y = 0.25x.</h3>

In order to graph it, let us find some points for graph using table.

Plugging x=4, we get

y = 0.25(4) = 1.

Plugging x=8, we get

y = 0.25(8) = 2.

<h3>We got two coordinates, (4,1) and (8,2).</h3>

Plotting those points on the graph and joining the points.

We can see that graph represents the proportional relationship.

Factor completely 3bx^2 - 9x^3 - b + 3x​
Anna11 [10]

Factor out the common terms in the first two terms, then in the last two terms;

3x^2(b - 3x) - (b - 3x)

Factor out the common term b - 3x

<u>= (b - 3x)(3x^2 - 1)</u>

Help me find the range of this function please
lara31 [8.8K]

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

f(x)=-2x-18

f(-8)=-2(-8)-18

f(-8)=16-18

f(-8)=-2

The first value of the range of the function is -2

- For x = -2

f(x)=-2x-18

f(-2)=-2(-2)-18

f(-2)=4-18

f(-2)=-14

The second value of the range is -14

- For x = 4

f(x)=-2x-18

f(4)=-2(4)-18

f(4)=-8-18

f(4)=-26

Th third values of the range is -26

- For x = 16

f(x)=-2x-18

f(16)=-2(16)-18

f(16)=-32-18

f(16)=-50

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}
