Answer:
Choice A) x and f(x) approach negative infinity
Choice D) x and f(x) approach positive infinity
Step-by-step explanation:
A cubic curve starts low and ends high if the leading coefficient is positive, which in this case it is. This means that the left side of the graph falls while the right side rises. Your teacher might say something like "fall to the left, rise to the right" to describe what the end behavior is doing.
More formally "fall to the left" means that as x approaches negative infinity, y = f(x) is approaching negative infinity as well. Similarly, "rise to the right" indicates that as x approaches infinity, y = f(x) heads off to infinity as well. Both x and y = f(x) move in the same direction along their respective number lines; eg, if one goes in the negative direction, then so does the other.
The graph below confirms the answer visually.
Answer:
$66.50
Step-by-step explanation:
Given that
she bought seven 1.45 rolls
Three 7.60 sweet loaves
and four 8.40 sweet rolls
We need to find out how much she paid in total
So,
= 7 × 1.45 + 3 × 7.60 + 4 × 8.40
= $10.15 + $22.80 + $33.60
= $66.50
Hence, she paid in total of $66.50

<span>. Given numbers : 16 x 34
Solution: Use distributive Property of multiplication
=> 16 x 34
=> let’s start with one value going to the left
=> 6 x 4 = 24, bring down 4 carry 2
=> 4 x 1 = 4 + 2 = 6 (the partial answer is 64)
then the tens value of the multiplier
=> 3 x 6 = 18 , bring down 8 carry 1
=> 3 x 1 = 3 + 1 = 4 (we have another partial answer as 480)
Last is to add the total amount
=> 64 + 480 = 544</span>
