The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

Given interval: -2 ≤ x ≤ 2




Substituting the values into the equation:

Answer:
33
Step-by-step explanation:
3*4*2.75=33
Answer: y = -3(x +
)² +
,
,
<u>Step-by-step explanation:</u>
First, you need to complete the square:
y = -3x² - 5x + 1
<u> -1 </u> <u> -1 </u>
y - 1 = -3x² - 5x
y - 1 = -3(x² + 
y - 1 + -3(
) = -3(x² +
+
)
↑ ↓ ↑
= 
y - 1 -
= -3(x +
)²
y -
-
= -3(x +
)²
y -
= -3(x +
)²
y = -3(x +
)² +
Now, it is in the form of y = a(x - h)² + k <em>where (h, k) is the vertex</em>
Vertex =
,
Answer:
24
Step-by-step explanation:
y= 24-4x
