Question

A graph of a quadratic function is shown below. graph of y equals negative 2 times x squared plus 40 x plus 600 Which of the following coordinates is not an intercept for the function?

Answer 1

Option c. (0,800)

Explanation:

The options for your question are attached in th epicture below

The function represented in the graph is

y = -2*x^2 + 40*x + 600

We just need to verify if each ordered pair belongs to the function

a. (-10,0)

y = -2*(-10)^2 + 40*(-10) + 600

y = 0

It is an intercept

b. (0,600)

y = -2*(0)^2 + 40*(0) + 600

y = 600

It is an intercept

c. (0, 800)

y = -2*(0)^2 + 40*(0) + 600

y = 600 ≠ 800

It is not an intercept
