Noah needs to order some new supplies for the restaurant where he works. The restaurant needs at least 503 knives. There are currently 391 knives. If each set on
sale contains 10 knives, which inequality can be used to determine x, the minimum
number of sets of knives Noah should buy?

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
