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
Answer:
(n/2)+5
Step-by-step explanation:
With n representing the unknown number, to get half of that number, divide the number by 2. n/2. Then, increase that quotient by 5.
(n/2)+5
The x coordinate stays the same but y coordinate changes sign so it will be a reflection in the x-axis.
First you need to know the definition of a complementary angle. That means that two angles add up to 90 degrees, or a right angle.
To find an angle complementary to a 78 degree angle, you need to subtract 78 from 90.
90 - 78 = 12
