Ya gotta use the Pythagorean theorem :)
a² + b² = c² (reminder: c is the hypotenuse)
4² + 8² = c²
16 + 64 = 80
√80 = 8.94
H = 8.94
Answer:
one to one function
Step-by-step explanation:
f(x)=6x+1 can only be a one to one function when x1=x2
Now,
f(x1)=f(x2)
or, 6x1 + 1 = 6x2 + 1
or, 6x1 = 6x2
or, x1 = x2
So f(x)= 6x + 1 is a one to one function

Answer:
a. Domain - x= all real numbers
b. Domain - x= all real numbers except 0
c. Domain - x= all real numbers
d. Domain - x= All real numbers
Step-by-step explanation:
The domain of a function is all the possible x values. It is easy to solve for domain by graphing the function.
a graph - blue
b graph - red
c graph - green
d graph - purple
