Answer:
Step-by-step explanation:
f'(x)=-2x+7
f(x) is decreasing if '(x)<0
so -2x+7<0
or 7<2x
or 2x>7
or x>7/2
including end points f(x) is decreasing in [3/2,∞)
Do 18-22 and that should give you the answer then to make sure your answer is correct subtract 22 from the answer you got
Answer:
Step-by-step explanation:
PEDMAS
P - Parenthesis
E - Exponents
D - Division
M - Multiplication
A - Addition
So, 2(5-3)^3+6^2
5 - 3 should be completed first as it is inside parenthesis
2(5-3)^3+6^2 = 2 *2^3 + 6^2
= 2 * 8 + 36 {exponents}
= 16 + 36 {Multiplication}
= 52
Answer:
all of them are sum by 15
Step-by-step explanation:
3 + 15 = 18 + 15 = 33 + 15 = 48
Check the picture below.
a vertical line has a slope of <u>undefined</u>, so can't quite use the slope-intercept form with it.
