Answer:
The area of the searched region is 
Step-by-step explanation:
If you want to find the area of a region bounded by functions f(x) and G(x) between two limits (a,b), you have to do a double integral. you must first know which of the functions is greater than the other for the entire domain.
In this case, for 0<x<1, f(x)<g(x)
while for 1<x, g(x)<f(x).
Therefore if our domain is all real numbers superior to 0 (where the limit 0<a<1 and 1<b), we have to do 2 integrals:
A=A(a<x<1)+A(1<x<b)
Answer:
y=-5,-3,-1,1 are value for y
Answer: D
Step-by-step explanation:
A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18
a+b = 12 + 18 = 30
Answer:
f(-4)= 2(-4)+2 =-8+2=-6
f(-2)= 2(-2)+2= -4+2=-2
f(1) = 2(1) + 2= 4
f(3) = 2(3) +2 =8
Step-by-step explanation:
Actually the domain is the value of the x that are allowed. Or, other words you can assume that it is the set of input values that are allowed. And through it we find the set of output values, or what we know as a range. So 6,-2, 4 and 8 here forms the range.
