X=9
Answer: D) 12
Step-by-step explanation:
As you can see side A is 6 and side B is also 6 so side C must be 12
Answer:
Zero of the function;
f(x) = 0 at x = -1.333
Discontinuity;
x = 1
Step-by-step explanation:
To determine the zero of the function;
we simply graph the function as shown in the attachment below.
From the attachment, we can deduce that f(x) = 0 at x = -1.333
To determine the discontinuity or the undefined points of the function, we simply equate the denominator to 0 and solve for x;
x - 1 =0
x = 1
The function is therefore not defined at the point where x =1
