Since you are essentially multiply the y value of f(x) by 3, you are stretching it vertically by a factor of 3.

Answer:

A. It is stretched vertically by a factor of 3.

Step-by-step explanation:

Given are two functions

f and g

f(x) = (x+2)^2

i.e. f is a parabola with vertex at (-2,0) open up

g(x) = 3(x+2)^2

This is also a parabola with vertex at (-2,0) open up

g(x) = 3 f(x)

This means f(x) is smaller vertically than g(x)

Or f(x) is stretched vertically by a factor of 3 to get g(x)

Hence option A is true.

A. It is stretched vertically by a factor of 3.

Tim poured 0.5 liters of water into a beaker and then added 300 milliliters more. What was the total amount of water in the beak
SVETLANKA909090 [29]
So, Using your conversion chart(if you have one) you'd see 1 liter makes 1000 milliliters. So, if you have half of a liter(0.5), then you have 500 milliliters. If he adds 300 more, then you get 800 milliliters total, which is also equal to 0.8 liters. Hope this helps!
