It needs to be multiplied by 20%, aka 0.2 in decimal form
Please use " ^ " to denote exponentiation:
<span>f(x) = –(x + 8)^2 – 1
Find the first derivative: f '(x) = -2(x+8)(1)
Set this = to 0: -2(x+8) = 0
solve for x: x = -8
Divide the number line into subintervals based upon x=-8:
(-inf, -8) and (-8, inf)
Choose a test value for x from each interval, e. g., -10 from the first interval and 20 from the second.
Subst. this test value into the derivative, shown above.
If the result is + the function is incr on that interval; if - the fn. is decr.

Question:
Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Select all that apply.


(3.6,0.6)
(-2.6,0.4)
(-3.6,0.6)
(2.6,0.4)
(4.5,-1.5)
Answer:
Option A :
is the solution to the system of equations.
Option D:
is the solution to the system of equations.
Explanation:
The two equations are
and 
To determine the solution of the system of equations using technology, let us plot the equations in the graphing calculator.
The solution of the system of equations is the intersection of the two lines.
Thus, from the graph, we can see that the two lines f(x) and g(x) intersect at the points
and 
Rounding off the solution to the nearest tenth, we get,
and 
Thus, the solution to the system of equations is
and 
Hence, Option A and Option D are the correct answers.
