observation : graph is opening up, means end behaviour is same that is graph is ending in the same side .
so the graph must represent a even degree polynomial .
observation : graph is opening on the positive side of the y axis .
it means the leading coefficient of the polynomial must be positive .
so we are looking for the option which have even degree and the leading coefficient is positive . the correct option is b .
first we need to set up our variables:
x = first number
x + 1 is our second number
x + 2 is our third number
x + 3 is our fourth number
now we make our equation for the sum of these four consecutive integers:
x + x + 1 + x + 2 + x + 3 = 354
after gathering like terms we have:
4x + 6 = 354
subtract 6 from both sides of the equation results in:
4x = 348
next we divide both sides by four:
x = 87
to check our work we plug 87 to our other variables and get
x + 1 = 88
x+ 2 = 89
x + 3 = 90
87 + 88 + 89 + 90 = 354 is true so our solution worked. the least integer is 87.
