Answer:

The graph of given function is shown below.

Step-by-step explanation:

The given function is

f(x)=\frac{x^2+5x+6}{x+3}

Factorize the numerator.

f(x)=\frac{x^2+3x+2x+6}{x+3}

f(x)=\frac{x(x+3)+2(x+3)}{x+3}

f(x)=\frac{(x+2)(x+3)}{x+3}

Cancel out the common factor.

f(x)=x+2

It is a straight line because it is a one degree polynomial.

At x=0,

f(0)=0+2=2

The y-intercept of the function is (0,2).

Put f(x)=0

0=x+2

x=-2

The x-intercept of the function is (-2,0).

Equate the cancel factor equal to 0, to find the hole of the function.

x+3=0\Rightarrow x=-3

The function has hole at x=-3.

The graph of given function is shown below.

The sum of two numbers is 45 and the different is 21.what are the numbers
ryzh [129]
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12

Part 1:the answer is 1/36
each time we roll the dice, the whole probabilities are 6
if we roll it two times
6*6=36

part 2

it's 1/8

each time we flip a coin, the whole probabilities are 2

if we flip it 3 times

2*2*2=8




good luck
