Complete the table of values for y= x^2-2x-3

Levart [38]

Answer:

x=3,y=0

x=-1,y=0

Step-by-step explanation:

We will have to factorise to get the value of x before solving for y

Let's solve

y=x^2-2x-3

To factorise x

x^2-3x+x-3

x(x-3)+1(x-3)

(x-3)+(x+1)

x-3=0

x=3

x+1=0

x=-1

Let's substitute the value of value to get the value for y

y=x^2-2x-3

When x is 3

y=3^2-2(3)-3

y=9-6-3

y=0

When x is-1

y=(-1)^2-2(-1)-3

y=1+2-3

y=0

Therefore when x is 3,y is 0

When x is -1,y is 0

What is the domain and range of each function?

liubo4ka [24]

Answer:

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

Step-by-step explanation:

The domain is the set of all x values in the function. The range is the set of all y values in the function. It is written in parenthesis from least to greatest. Do not repeat values even if the function has them more than once.

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

Answer:

48/37 + (8/37)i.

Step-by-step explanation:

8 / (6 - i)

We multiply top and bottom of the fraction by the conjugate of 6 - i , which is 6 + [email protected]

= 8*(6 + i) / (6 - i)(6 + i)

= 48 + 8i / (36 + 6i - 6i - i^2)

= 48 + 8i / (36 - (-1))

= 48 + 8i / 37

= 48/37 + (8/37)i.

Which shows the equation 3y – x = 6 written in slope-intercept form?

laila [671]

Slope intercept form : y = mx + b

3y - x = 6 ....add x to both sides
3y = x + 6 ...divide both sides by 3
y = x/3 + 2 <== slope intercept form
