A Function F Is Given By F(4x-1) = 4x2+5. Evaluate F(15).

A function f is given by f(4x-1) = 4x2+5. Evaluate f(15).

 

Answer:905 would be the answer if the function were defined as f(x) = 4x^2+5:

Step-by-step explanation:

But the function is defined as f(4x-1) = 4x^2+5. To evaluate f(15), you need to determine the value of x that makes 4x-1 equal to 15.

4x-1 = 15

4x = 16

x = 4

THAT is the value you need to substitute into the expression 4x^2+5 to get the answer.

Contains mostly nitrogen, oxygen, carbon dioxide. These gases are constantly added and removed. The atmosphere is divided into five different layers because the atmosphere is not uniform therefore its properties change with altitude. It holds the oxygen we need to breathe. The Earth's atmosphere performs some optical tricks: The blue color of the sky. The white color of the clouds. The red sunrises/sunsets. The yellow sun. Aurora's Code 11.22.1.3.

Which Of The Following Polynomials Is Exactly Divisible By (3x + 1)?, A. 6x^2 + 17x + 5 , B. 9x^2+ 6x + 1 , C. 3x^3 + 4x^2 2013 8x 2013 3, D. All Of T

Which of the following polynomials is exactly divisible by (3x + 1)? a. 6x^2 + 17x + 5 b. 9x^2+ 6x + 1 c. 3x^3 + 4x^2 – 8x – 3 d. all of the above   Answer: The correct answer is letter a. 6x^2 + 17x + 5. Step-by-step explanation: In finding the correct polynomial that is exactly divisible by (3x + 1), we need to do a trial and error. Divide each polynomial to (3x + 1) and if it gives a quotient without any remainder then that is the correct answer. After solving the given three polynomials one by one, the correct answer is letter a. 6x^2 + 17x + 5. Code 10.3.1.2.
