Based on the given texts in the table about the graph of the function, the true statements are:
- The graph crosses the y-axis at (0,-15).
- The graph has a point of discontinuity at x = -2.
- The graph is increasing over the interval (4, ∞o).
- The domain of the function is all real numbers.
The function, 4x - 15 shows that 15 is the y-intercept which means that the graph will cross the y-axis at (0,15).
The point of discontinuity is x = - 2 and we see this with the gap created at x < -2 and -2 ≤ x ≤ 4.
The graph is indeed increasing over the interval (4, ∞o) because any value of x that is greater than 4 will increase f(x) = .
The domain of the function is also all real numbers as it begins at negative infinity and ends at infinity, (-∞, ∞).

Answer:
The ratio of their corresponding side lengths is equal to
Step-by-step explanation:
step 1
<em>Find the scale factor</em>
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z-------> the scale factor
x----> the area of the smaller solid
y----> the area of the larger solid
so
In this problem we have
substitute
square root both sides
------> scale factor
Simplify
step 2
<em>Find the ratio of their corresponding side lengths</em>
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
In this problem we have that the scale factor is equal to
therefore
The ratio of their corresponding side lengths is equal to
