An inequality that represents Denise's goal in terms of the number of hours spent running 'h'

$550h\leq 5000$

Given :

Denise wants to burn at least 5000 calories a week through running.

she can burn 550 calories per hour

Let 'h' be the number of hours spent

In 1 hour she can burn 550 calories

In 'h' hours she can burn 550h calories

Given that she want to burn atleast 5000 calories in a week

Burn atleast 5000 calories means <=5000 calories

So , the inequality that represents Denise's goal is

calories burn in h hours <= 5000 calories

$550h\leq 5000$

Respond to each of the following questions. Be sure to include and thoroughly describe each transformation.

sergeinik [125]

Answer:

31. 1) Vertical shift up 4 units.

2) Horizontal shift right 1 unit.

3) Vertically stretched by a factor of 3.

32. $g(x)=-(x+3)^2+7$

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

- If $f(x)+k$ , the function is shifted up "k" units.

- If $f(x)-k$ , the function is shifted down "k" units.

- If $f(x+k)$ , the function is shifted left "k" units.

- If $f(x-k)$ , the function is shifted right "k" units.

- If $-f(x)$ , the function is reflected over the x-axis.

- If $bf(x)$ and $b>1$ , the function is stretched vertically by a factor of "b".

31. Given the function $f(x)=x^{2}$ and the function $g(x) = 3(x - 1)^2 + 4$ , we can notice that the transformations from the graph of f(x) to the graph of g(x) are:

1) $f(x)+k$

2) $f(x-k)$

3) $bf(x)$ , being $b>1$

Therefore, we can conclude that the transformations necessary to transform the graph of f(x) to the graph g(x) are:

1) Vertical shift up 4 units.

2) Horizontal shift right 1 unit.

3) Vertical stretch by a factor of 3.

32. Knowing the parent function:

$f(x)=x^{2}$

And given the transformations:

1) Reflection over the x-axis.

2) Horizontal shift left 3 units.

3) Vertical shift up 7 units.

We can define that the function g(x) is:

$g(x)=-(x+3)^2+7$
