Examine the following piecewise function.
miss Akunina [59]

By analyzing when the piecewise function increases and when it decreases, we can conclude that the true statement is:

"The function is increasing over the interval −8≤x≤−2."

<h3>Which statements are true?</h3>

We know that our function is made of straight lines that connect:

  • Point (-8, 3) with (-2, 8)   {This is an increasing line}
  • Point (-2, 8) with (2, 8)   {This is a horizontal line}
  • Point (3, 0), and (7, -7)   {This is a decreasing line}

(to see if it increases or decreases, compare the y-value of the second and first point. If the second is larger, then the line increases).

Then the statement that is true is:

3) "The function is increasing over the interval −8≤x≤−2."

mafiozo [28]

Answer:

16

Step-by-step explanation:

To solve, we can use an equation finding the average of the siblings'ages.

\frac{14 + 12 + x}{3}  = 14 \\  \ 14 + 12 + x = 42 \\ x = 42 - 14 - 12 \\ x = 16

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(1). 2 8 10 4
Klio2033 [76]
Hello!

You can solve this by plugging 1 into g(x) and plugging the result into h(x).

g(x) = 2x
g(1) = 2(1)
g(1) = 2

h(x) = 2x + 4
h(g(1)) = 2(2) + 4
h(g(1)) = 4 + 4
h(g(1)) = 8

Answer:
<span>(h ∘ g)(1) = 8</span>
