Calculation of relative maxima and minima of a function f (x) in a range [a, b]:
We find the first derivative and calculate its roots.
We make the second derivative, and calculate the sign taken in it by the roots of the first derivative, and if:
f '' (a) <0 is a relative maximum
f '' (a)> 0 is a relative minimum
Identify intervals on which the function is increasing, decreasing, or constant. G (x) = 1- (x-7) ^ 2
First derivative
G '(x) = - 2 (x-7)
-2 (x-7) = 0
x = 7
Second derivative
G '' (x) = - 2
G '' (7) = - 2 <0 is a relative maximum
answer:
the function is increasing at (-inf, 7)
the function is decreasing at [7, inf)
Step-by-step explanation:
in traingle ABD
SIN45=AD/AB
1/√2=7/AB
AB=7√2
PERIMETER=SUM OF ALL SIDE=2(AB+AD)=2(7√2+=14√2+14
Answer:
16 outcomes
Step-by-step explanation:
4 outcomes for spinner
2 outcomes for 1st coin
2 outcomes for 2nd coin
4 x 2 x 2 = 16
Answer:
There is no x-intercept, only a y-intercept, which would be 1
I believe the answer should be C.
I am not sure how to do that method... I only know this. (heehee)
