For the function , f(x) = 2x + 1. If f(x) = 3 , what is the value of x?
kodGreya [7K]

Answer:

For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").

an insulated tote bag has a volume of 972 cubic inches. if the base of the tote bag is a square with an area of 81 square inches
xxMikexx [17]

Answer: The height is 12 inches.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume: area x height

Replacing with the values given:

972 cubic inches = 81 square inches x h

Solving for h (height)

972/81 = h

12 inches =h

The height is 12 inches.

Feel free to ask for more if needed or if you did not understand something.
