The average rate of change of a continuous function <em>f(x)</em> in an interval (<em>a</em>, <em>b</em>) is
(<em>f(b) </em>- <em>f(a)</em>) / (<em>b</em> - <em>a</em>)
So for
<em>f(x)</em> = 3<em>x</em> ² + 2<em>x</em> + 5
on the interval (0, 2), we have
• <em>f</em> (2) = 3 • 2² + 2 • 2 + 5 = 21
• <em>f</em> (0) = = 3 • 0² + 2 • 0 + 5 = 5
so that the average rate of change is
(<em>f</em> (2) - <em>f</em> (0)) / (2 - 0) = (21 - 5) / 2 = 16 / 2 = 8
and the answer is B.

Answer:
12b+6e+9
Step-by-step explanation:
You multiply 3 with every number inside the parentheses.
(3x4b)=12b
(3x2e)=6e
(3x3)=9
Step-by-step explanation:
4⁵ × 4^-7 / 4^-2
it is important to understand that a negative exponent means 1/...
a^-n = 1/(a^n)
in that sense we have therefore
4⁵ × 1/4⁷ × 4² (as (1/ 1/a^n) = a^n)
4⁵ × 4² × 1/4⁷ = 4⁷ × 1/4⁷ = 1
so, "1" is the fully simplified expression equal to the original expression.
The y- intercept is 4. M= 2/3
