Answer:
(-2.4, 37.014)
Step-by-step explanation:
We are not told how to approach this problem.
One way would be to graph f(x) = x^5 − 10x^3 + 9x on [-3,3] and then to estimate the max and min of this function on this interval visually. A good graph done on a graphing calculator would be sufficient info for this estimation. My graph, on my TI83 calculator, shows that the relative minimum value of f(x) on this interval is between x=2 and x=3 and is approx. -37; the relative maximum value is between x= -3 and x = -2 and is approx. +37.
Thus, we choose Answer A as closest approx. values of the min and max points on [-3,3]. In Answer A, the max is at (-2.4, 37.014) and the min at (2.4, -37.014.
Optional: Another approach would be to use calculus: we'd differentiate f(x) = x^5 − 10x^3 + 9x, set the resulting derivative = to 0 and solve the resulting equation for x. There would be four x-values, which we'd call "critical values."
1 out if 20 you would get right
There is 5 questions 4 answers to pick from so 5 times 4 is 20
Then they said what is the probability of only getting one answer right
So the answer would be 1 out of 20 1/20
Answer:
BELOW
Step-by-step explanation:
DO I HEAR 100 POINTS? Yes.
For the first image, that answer is A.
For the second image, I'm a bit confused on which problems you want me to do, so I'll do number 10, 11, and 14.
10) Yeah, you're correct, it is J.
11) (1,-6), (-2,-5), (8,2) (4,0) and I can't see the last point so..
14) Can't see the question :(
