Answer:

Using the vertical line test, the functions are b, c, d, and f

Step-by-step explanation:

a and e both fail the vertical line test, therefore, it's not a functions.

B, c, d, and f are functions because they pass the vertical line test. If you were to draw a straight line down the graph, the points would only touch the line once. A and E however, touch the line two or more times.

Answer:

*In Explanation

Step-by-step explanation:

<u>1) Start by just substituting the value of x (given in equation 1) into the second equation:</u>

y = 3x - 1

y = 3(2) - 1

y = 6-1 = 5

<u>2) Since both equations have x on one side, make both equations equal to one another:</u>

2y + 4 = 9 - 3y

<u>Solve for y:</u>

5y = 5

y = 1

<u>Plug y = 1 into either one of the given equations and solve for x:</u>

I'll use first equation:

x = 2y + 4

x = 2(1) + 4

x = 6

<u>3) When substituting X into the second equation, remember to use parenthesis:</u>

The student was substituting x from equation 1 into equation 2, but they forgot to multiply ALL of 2y + 3 by 2.

x = 2y + 3

Substitute into 2nd eqn:

y = 2(2y + 3) - 9

Which shows one way to determine the factors of 12x3 – 2x2 + 18x – 3 by grouping?
Debora [2.8K]

Option A

2x^2(6x-1) + 3(6x-1) is one way to determine the factors of 12x^3-2x^2+18x-3 by grouping

<em><u>Solution:</u></em>

Factoring by grouping means that you will group terms with common factors before factoring

<em><u>Given expression is:</u></em>

12x^3-2x^2+18x-3

Group the first two terms together and then the last two terms together.

(12x^3-2x^2)+(18x-3)

We can see that 2x^2 is common in first two terms

And 3 is common in last two terms

Factor them out

(12x^3-2x^2)+(18x-3) = 2x^2(6x-1) + 3(6x-1)

2x^2(6x-1) + 3(6x-1)

Thus option A is correct

A function, f(x) = 4x + 5, has a domain 0 &lt; x &lt; 50. What is its range?
Roman55 [17]

Answer:

f(x) = 4x+5 ; 0 ≤ x ≤ 50

 

The range is the possible output values of f(x)

 

4(0) + 5 = 5       smallest output value in range

4(50) + 5 = 55    largest output value in range

 

The outputs are between 5 and 55 including the endpoints so

the range is [5, 55]
