F(x)=-x+12/4 Not sure if this is right..
Domain is what you can put in
the domain for most functions is ALL REAL NUMBERs
except for those that violate the dividing by zero thingummy
example
if yu had
f(x)=x+2
domain is all real numbers
f(x)=2/x
domain is all real numbers except for 0 since cannot divide by 0
f(x)=2(x-4)
domain is all real numbers except for 4
so answer is {x|x is a real number}
Answer:
Sorry I can't understand.
Answer:
A = 102 cm^2
Step-by-step explanation:
This figure is a trapezoid. The area is given by
A = 1/2 (b1+b2) *h where b1 is the base and b2 is the top
b1 = 21 b2 = (6+7) and h = 6
A = 1/2 (21+13) *6
A = 1/2 (34)*6
A = 102 cm^2
