What are the options that you can choose from???
Answer:
x different from 2
Step-by-step explanation:
The function is written as the quotient:
that can give us a real value for any value of x except for x=2 that creates a ZERO in the denominator, making the division undefined.
So the only value for which the function cannot be evaluated is x=2, therefore the function's domain is all the real numbers except for x=2.
Just pretend f(x) is y bc they mean the same thing
Soo if x=-1
5(-1)-7=y
-5-7= -12
Area of a triangle = 1/2 x base x height:
Area = 1/2 x 8 x 3x = 12x
Perimeter = sum of the 3 sides:
4x-3 + x +9 + 8 = 5x +14
Answer: C. 12x; 5x+14
