Question

All you need is in the photo please answer all the 3 questions

Answer 1

a) y =2^x

b) Exponential

c)

a) According to that graph, we have point (1,2) and (2,4) since that exponential function is

`\begin{gathered} y=a(b)^x \\ 1=a(b)^0\rightarrow a\text{ =1} \\ 4=ab^2\text{ }\rightarrow4\text{ =}b^2\rightarrow\text{ }b=2 \\ y=2^x \end{gathered}`

Since the function is increasing, due to its direction, we can write y =2^x

b)The type of function is exponential, since x= 0, y = 1, and due to its shape.

3) As we can see the shape of the graph is curve,
