Which graph represents the function?

f(x)=√x-1    My answer= Last Graph b/c (1,0) is the x-intercept. Am I right?

At the Smith, Inc. company, the number of employees needed to work per year is modeled by the function f(x).

f(x)=500/1+19e^−0.6x

Which statements are true about the number of employees?

The company started with 20 employees.

The maximum number of employees for the company is 500.

The third year is the first year in which the company will have more than 100 employees.

The rate of the number of employees per year increases for all values of x.

My answer= The second and third statements are the only statements correct. Am I right?

Thanks for checking my work.
