F(x)=x^2-3x-2 is shifted 4 units left. The result is g(x) what is g(x)

grandymaker [24]

To solve this problem you must apply the proccedure shown below:

1. If the function $f(x)=x^{2}-3x-2$ is shifted $4$ units left, this means that you must substitute the value of $x$ by $x+4$ to find $g(x)$ , as following:

$f(x+4)=(x+4)^{2}-3(x+4)-2$

2. Now, expand the function:

$f(x+4)=x^{2} +8x+16-3x-12-2\\ f(x+4)=x^{2} +5x+2$

3. Then, you have that $g(x)$ is:

$g(x)=x^{2} +5x+2$

Therefore, the answer is: $g(x)=x^{2} +5x+2$

Candace makes a sugar-water mixture for hummingbirds. She knows the amount of sugar used in the mixture is proportional to the a

Sonja [21]

Answer:

the first image (the image with the upward sloping line)

Step-by-step explanation:

If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.

If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

The height of a giant redwood tree is 200 feet, and the height of an oak tree is 120 feet. Taking the height of the redwood tree

marta [7]

Answer:

$\% Change = \frac{|120-200|}{200} *100 = 40\%$

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree

Step-by-step explanation:

For this case we can calculate the % of change with the formula of relative change given by:

$\% Change = \frac{|New -Base|}{Base} *100$

For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base

And the New value would be 120 who represent the height of the oak tree

If we replace into the formula we got:

$\% Change = \frac{|120-200|}{200} *100 = 40\%$

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
