Im pretty sure its c hope I could help
Answer:
a rate is a special type of ratio that compares 2 DIFFERENT quantities while a ratio is a comparison of 2 quantities BY DIVISION
a percentage is a rate, number, or amount in each hundred.
step-by-step explanation
u can see percentages in stores like 30% off. If the price of the product is $2.99 you have to multiply 2.99 by 30% equal 0.3, then do 2.99 - 0.3 = $2.69
a rate is this 200\5 = 40\1
a ratio is this <u>3 to 4 or 5 for every 3</u>

To find the value of f(3) we need to follow the below steps :
Step 1 : First plot the graph of f(x)
Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)
Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .
Step 4 : Now there exists two cases :
If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x
If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
If this is wrong than I guess I wasn't smart enough :)
