Directions: Determine whether each statement is true or false.
3
1. The expression f(x) does not mean "f times X".
2. The relation {(1,4), (2,4), (3,5), (6,10) is quadratic function
3.In the function y = f(x), x is the independent variable and y is the
dependent variable.
4. In the definition of function, set x is called the domain of the function.
5 The function g(x) = x (x - 2) is a quadratic function​

Answer:

1. True

2. False (Not sure if it correct, Correct me if i'm wrong)

3. False

4. True

5. A quadratic function is of the form

f(x)=ax2+bx+c

Notice that the highest power of this polynomial is  2 . That’s why we say a 2nd degree/order polynomial is a quadratic function.

For the case of  y=x2  we have the following…

f(x)=1⋅x2+0⋅x+0

Notice that  b=c=0 , but  a≠0 , and this is exactly what we need. Because if  a=0 , it reduces down to a zero degree equation, that’s simply a horizontal straight line. Final Answer (True)
