Question

Find two values of x such that f(x)=-3
I don't understand what this question is asking.

Answer 1

You haven't stated the question in its entirety, perhaps thats why you dont understand what is being asked. Go back to the source of this problem and retype the entire question.

Answer 2

Consider the graph: Bad drawing graph points are (2,0), (-2,0), (0,-4)


a. find f(-1)-- I got -3
b. Find f(2)-- I got 0
c. find f(3)--I got 5
d. Find two values of x such that f(x)=-3

Answer 3

The two values are x = -1 and x = 1.

Why? Because at x = 1 and x = -1, the y-coordinate is - 3. When you want f(x) = -3, you are looking for values of x such that the function, called y, will have a value of - 3, and that occurs at x = -1 and x = 1.

Answer 4

Okay, that's makes sense. Thank you

Answer 5

You're welcome.
