In the following list identify a function with graph through the points

[5; 0]

and

[- 1; - 2]

y = \log_{2} (x + 3) - 3

y = \log_{5} (10 - x) - 1

y = \log_{3} (4 + x) - 2

y = 2 - \log_{3} (4 + x)

y = 3 - \log_{2} (x + 3)

y = 1 - \log_{5} (10 - x)

a \in (0; \infty)

b = 5 a

a \in (0; \infty)

b = \frac{10}{a}

a \in (0; \infty)

b = \frac{25}{a}

a \in (0; \infty)
