A botanist (plant biologist) studies a plant called Foxtail Ferns for a living. (How exciting.) She is interested in doing an experiment to see what
combination of temperature and humidity they grow best in. So, she sets up
four different rooms: ROOM ONE is High Temp, High Humidity. ROOM
TWO is High Temp, Low Humidity. ROOM THREE is Low Temp, High
Humidity. ROOM FOUR is Low Temp, Low Humidity. She puts ten Foxtail
Ferns in each of these rooms. At the end of the week-long experiment, she
measures the Ferns' height and finds the average height of the plants in each
room. For this experiment, what is the I. V. (Independent Variable)?
O The height of the plants after one week
O Foxtail Ferns
Which room (temp/humidity combination) the plants are in

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.  

it would have to be 3/0
