Answer:
D. The domain of F(x) is all real numbers.
E. It is increasing.
Step-by-step explanation:
Given the function
f(x) = 2 • 5x
y intercept occurs at x = 0
f(0) = 2 • 5(0)
f(0) = 2 • 0
f(0)= 0
Hence the y intercept (0,0)
The domain are the input values x that makes the function exists. According to the function, the function f(x) will exist for al values of x hence the domain of F(x) is all real numbers.
If x = 0, f(x) = 0. This shows that the range of the values is y >0
The value of function f(x) also increases for increasing value of x, hence it is increasing
