Use the graph of the quadratic function y = x2 + x + 4 to answer the question. what are the zeros of the function? –2 and 4 4 and 0 4 and –4 –8 and –4

Answer.

A. -2 and 4

Step-by-step explanation:

If you mean't for the question to really be "Use the graph of the quadratic function y = -1/2x^2 + x + 4 to answer the question.

"

What are the zeros of the function?

–2 and 4

4 and 0

4 and –4

–8 and –4

The answer is A. -2 and 4

(I just took the unit test on e.d.g.e)

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
