The third graph or bottom left graph represents 
Step-by-step explanation:
Step 1:
To determine which of the given graphs represents the equation
, we substitute some values in the place of x.
When

Anything with an exponent of 0 will equal 1.
So the graphs on the right side cannot be the answers.
Step 2:
Now we substitute another value to determine which graph represents 
When

The value of f(x) when
is lesser than the value of f(x) when 
So the third graph or bottom left graph represents 
Answer:
d
Step-by-step explanation:
If x represents the slant height, the graph would be a straight line.
If x represents the radius, the graph would be a parabola.
Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.
We are looking for g(x). Answers a and b are wrong.
In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.
So the domain is x > 5.
d is your answer.
FACTORISATION IS BASICALLY FINDING LIKE-TERMS.
1. FIND THE HCF OF 8. HERE, THE HCF IS 8. ALSO, CHECK ALL THE LIKE-TERMS. LIKE-TERMS ARE OUTSIDE THE BRACKET AND UNLIKE TERMS ARE INSIDE.
2. ADD THE TERMS IN THE BRACKET AND THE TERMS OUTSIDE THE BRACKET FROM STEP 1.
8x + 8y + rx + ry
1. 8 (x + y) + r (x + y)
2. (x +y) (8+r)
Answer:
The correct option is B
