Choice C: Down and to the left

Since the value -3 serves as the y-intercept, the equation moves down.

Since the value -2 serves as the x-intercept, the equation moves to the left.

Keep in mind that the original standard equation of a parabola is in the form:

f(x) = a(x-h)^2 +k.

Since in the equation you presented us with has the value of h as a positive, that means that the "2" had to have been negative before placed in the equation, because then there would be two negatives which would turn the "2" into a "positive"

Just clarifying incase anyone would assume the answer to be down and to the right, which is wrong.

Therefore the correct answer choice is C.

Hope this helped!

As per your question, total cost of watermelon should end with either 5(for odd quantity) or 0(for even quantity).

If the quantity of watermelon is odd, then the total cost value of pineapple should end with 3 and this is not possible when the cost of pineapple is ₹7.

So let's come to conclusion that the count(quantity) of watermelon should be any one of 0, 2, 4, 6.

If count of watermelon is 6: It will cost ₹30 and for remaining ₹8, we can buy 1 pineapple but still ₹1 will not be utilised. So 1 pineapple is not possible

If count of watermelon is 4: It will cost ₹20 and for remaining ₹18, we can buy 2 pineapple with ₹4 not being utilised. So 2 pineapple is also not possible.

If count of watermelon is 2: It will cost ₹10 and for remaining ₹28, we can buy 4 pineapple with all amount being utilised. We can buy 4 pineapple along with with 2 watermelon for ₹38.

If count of watermelon is 0: It will cost you ₹0 and for remaining ₹38, we can buy 5 pineapple with ₹3 being not utilised. So 5 pineapple is also not possible.

So the answer is 4 pineapple.
