Answer:
- no
- no
Step-by-step explanation:
If the graph is not a straight line, it is not a linear function. Neither graph 1 nor graph 2 is a straight line, so neither is a linear function.

Graph 2 is made of parts of two straight lines. It is not one straight line, so not a linear function. It is called "piecewise linear," which is different.
X^2 - X - 12 all you had to do is Factor
3.21 (I did in on a triangle calculator)
The options are given in factored form.
If a function is zero at x=3, this means x=3 is a root of the equation. x = 3 can also be written as x - 3 = 0
So, if x = 3 is a root of the equation, x - 3 will be a factor of the function. From the given options we can see only Option C contains x - 3 as its factor. Substitute x = 3 in option C and the function value will be zero.
So, the correct answer is option C
