Answer:
Step-by-step explanation:
GIVEN: Catherine sells cupcakes c for each, The ingredients for each cupcake cost her , and the sum of all her other expenses is .
TO FIND: Equation to represent Catherine's profit from selling cupcakes.
SOLUTION:
Cost of ingredients for each cupcake
sum of all other expenses
Selling price of each cupcake
Total cupcakes sold
Now,
As we know that
putting values,
Hence the equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is
The sum of 5 consecutive integers is 120
third number = ?
third number will be the middle number of 5 consecutive integers
so if we divide 120 with 5 we get 24.
so 24 is the third number.
consecutive numbers are: 22, 23,24,25 and 26
22 + 23 +24 +25 +26 = 120
so, 24 is the third number

That's a quadratic, a nice parabola in vertex form.
The parabola has a positive x^2 term, so it's a CUP, concave up positive. It will have a minimum at the vertex, which is (2,5). Plot that point.
Now we need a couple of guide points to draw the usual parabola going up from both sides of its vertex. We try x=0 giving (0,9) and see that x=4 also gives 9, (4,9). Plot the parabola through those two points and the vertex and you're done.
