Answer:
9
Step-by-step explanation:
Just like a rectangle, times one length times width
When b=0
f(x)=ax^2+c
test each
A. with x^2-1, A is false
B. with -x^2-1, B is false
C. cannot find contradiction
D. the axis is actually x=0, 0 is nithere positive nor negative, false
answer is C
Answer:
D
Step-by-step explanation:
8 is LESS THAN 1/2x
so youd take those numbers and multiply by 1/2
C, B, and A are all under 8, so that would be wrong
when you multiply 1/2 with 17, you get 8.5 which is bigger than 8. then everything else above that is more than 8, therefore D is the right answer.
Answer:
Step-by-step explanation:
We were given the slope formula;
This line is vertical if the denominator is zero.
That is when 
This implies that;
Justification;
When , then, the line passes through;
and 
The slope now become
The equation of the line is
This implies that;
... This is the equation of a vertical line.
