True bc as you go along the horizontal (side to side) line or the x-axis, the x values never stop therefore they are all real numbers. can also be (negative infinity, positive infinity)

On a coordinate plane, a curved line labeled f of x with a minimum value of (1.9, negative 5.7) and a maximum value of (0, 2), c

deff fn [24]

Answer:

(a) F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)

Step-by-step explanation:

Wherever the function crosses the x-axis, its sign changes. This lets us make a map of the signs of the function, and identify intervals where it is positive and negative.

<h3>Sign changes</h3>

The x-intercepts are said to be at x ∈ {-0.7, 0.76, 2.5}. These three crossing points divide the graph into four (4) intervals. The sign of the function is given as positive at x=0 and negative at x = 1.9. So, our sign map is ...

< -0.7 . . . . . negative

-0.7 to 0.76 . . . . . positive (2 at x=0, for example)

0.76 to 2.5 . . . . . negative (-5.7 at 1.9, for example)

> 2.5 . . . . . positive

Choosing from the descriptions, the one that matches is ...

F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)

The pink trapezoid has been dilated to the blue trapezoid. What was the center of the dilation?

nalin [4]

Answer:

A) (0, 0)

Step-by-step explanation:

To find the center of dilation, draw lines from each pre-image point to the image point. A picture of this is attached.

Once we get these lines drawn, the center of dilation will be the intersection of these lines. The lines intersect at (0, 0), so this is the center of dilation.
