Step-by-step explanation:
Step-by-step explanation:
This will result to 3k+4=22 because minus times minus is plus
Therefore, 3k=22-4, when +4 crosses over the equals to sign it becomes -4
=> 3k=18
=> Divide both sides by 3 to get k
=> k=6
Answer:
9
Step-by-step explanation:
(3/2)^3 = 27/8
27/8 x 8/3 = 27/3 = 9
Let <em>f(x)</em> = (<em>x</em> ² - 1)³. Find the critical points of <em>f</em> in the interval [-1, 2]:
<em>f '(x)</em> = 3 (<em>x</em> ² - 1)² (2<em>x</em>) = 6<em>x</em> (<em>x </em>² - 1)² = 0
6<em>x</em> = 0 <u>or</u> (<em>x</em> ² - 1)² = 0
<em>x</em> = 0 <u>or</u> <em>x</em> ² = 1
<em>x</em> = 0 <u>or</u> <em>x</em> = 1 <u>or</u> <em>x</em> = -1
Check the value of <em>f</em> at each of these critical points, as well as the endpoints of the given domain:
<em>f</em> (-1) = 0
<em>f</em> (0) = -1
<em>f</em> (1) = 0
<em>f</em> (2) = 27
So max{<em>f(x)</em> | -1 ≤ <em>x </em>≤ 2} = 27.
