What is the vertex of f(x) = | 8x + 8| - 3?

Mathematics
1 answer:
Harman [31]3 years ago
3 0

Answer:

<h2>(-1, -3)</h2>

Step-by-step explanation:

Vertex of y = |x| have the coordinates (0, 0).

f(x) + n - shift the graph n units up

f(x) - n - shift the graph n units down

f(x + n) - shift the graph n units to the left

f(x - n) - shift the graph n units to the right

nf(x) - stretches/shrinks vertically

f(nx) - stretches/shrinks horizontally

We have

f(x) = |8x + 8| - 3 = |8(x + 1)| - 3 = |8| · |x+1| - 3 = 8|x + 1| - 3

g(x) = |x| → f(x) = 8g(x + 1) - 3

vertically streched by 8      (0, 8 · 0) → (0, 0)

shifted 1 unit to the left    (0 - 1, 0) → (-1, 0)

shifted 3 units down       (-1, 0 - 3) → (-1, -3)

What is this answer please help me
Deffense [45]

Answer:

It is proportional

Step-by-step explanation:

To determine if its proportional/non-proportional is by using ratios

so go line by line

p pine and k oak

12 pine to 44 oak

18 pine to 66 oak

24 pine to 88 oak

30 pine to 110 oak

Start with the first line

p= pine per k= oak

so obviously not numbers but to help mind you it just means the numbers will be put as p/k (to make life simpler)

Or pine over oak

Second Line

12/44 which reduces down to 3/11

Third Line

18/66 which reduces down to 3/11

Fourth line

24/88 which reduces down to 3/11

Fifth line

30/110 which reduces down to 3/11

In order to be proportional the ratios all have to be equivalent to each other

Therefore,

3/11 = 3/11 = 3/11 = 3/11

So this is proportional

3. In order to enter the state fair, there is
Anastasy [175]

Answer:

C = 8 + 3x

The rate of change in the above equation is 3 dollars per game and it interpret the cost per game.

The initial value in the above equation is 8 dollars, which interpret the entry fee that every one person has to pay to enter the fair.

Step-by-step explanation:

Let the admission cost of the fair is $x and each game is $3.

Now, Steven went to the state fair, played  4 games and spent a total of $20 on  admission and games.

So, we can write 20 = x + 4 × 3 {As the relation is linear}

⇒ x = $8

Therefore, the admission cost in the fair is $8.

Therefore, the equation that models the situation is  

C = 8 + 3x ............ (1)

Where C is the total cost and x is the number of games played.

So, the rate of change in equation (1) is 3 dollars per game and it interprets the cost per game.

Again, the initial value in equation (1) is 8 dollars, which interprets the entry fee that each person has to pay to enter the fair. (Answer)
