Question

Christian is training for a swimming competition He starts swimming 10 ft. from the shore to his boat The table below represents the distance from the shore. f(z), as a function of time after z minutes of swimming.

Answer 1

Answer: it goes up by 60 each time

Step-by-step explanation:

Answer 2

Answer:

f(x) = 20x + 10

Step-by-step explanation:

(0 , 10) ; (3 , 70)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

          $= \frac{70-10}{3-0}\\\\= \frac{60}{3}\\\\= 20$

y- intercept = 10

f(x) = mx + c

     = 20x + 10
