Question 15 (Multiple Choice Worth 1 points)

(03.05 LC)

The graph of a function f(x) is shown below:

plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3

What is the domain of f(x)?

integers from −1 < x < 2
integers from −3 < y ≤ 3
integers from −3 ≤ y < 3
integers from −1 ≤ x ≤ 2

Question 16 (Multiple Choice Worth 1 points)

(03.03 MC)

Choose the equation that represents the graph below:

Graph of a line passing through points negative 2 comma 0 and 0 comma negative 4

y = −2x − 4
y = 2x + 4
y = −2x + 4
y = 2x − 4

Question 17 (Ye

Answer 1

The domain is the x values in any point.

Therefor it would be −1 ≤ x ≤ 2

The other question:
(-2,0)(0,-4)
the y intercept is -4 because that's when x = 0 (as we previously discussed)
and all we need to do is find the slope
using :
y2-y1/x2-x1

Slope = -4/2
Slope = -2

so -2x - 4
