Which graph represents the function?

 

f(x)=√x-1

 

Graph of a square root function. The horizontal axis ranges from negative 3 to 7 in increments of 1. The vertical axis ranges from negative 2 to 8 in increments of 1. The function begins at begin ordered pair 0 comma 1 end ordered pair and passes through begin ordered pair 1 comma 3 end ordered pair and begin ordered pair 4 comma 5 and ordered pair.

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?

 

Select each correct answer.

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.
