Answer:
The answer for the given function is f( -12 ) = 240.
Step-by-step explanation:
Given:
To Find :
F ( -12 ) = ?
Solution:
Function:
- A function is like a machine that gives an output for a given input.
- A function has an independent variable which is called the input of the function.
- The output for a given input is called the dependent variable.
For Example
f ( x ) = x + 3
x = independent variable
f ( x ) = Output for a given input
Here we have
Therefore f(-12) = 240
For the first, simply plug in the value of x given (x = 2) into the equation:
So, 8 would be your answer.
For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.
For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.
