Answer: Options A and C.
Step-by-step explanation:
The parent exponential function has the form:
This can be transformated as following:
When you multiply the function by a factor <em>a</em> ()<em> </em>and <em>a>0 </em>, then the function is vertically stretched.
When you add a number <em>k</em> to the parent function, the function is shifted up ()
The parent function given in the problem is:
To obtain the function , the parent function is multiplied by a factor 3 (which is greater than 0) and the number 5 is added.
Therefore, the graph is shifted up and vertically stretched.
Answer:
Step-by-step explanation:
let f(x)=ab^x
when x=1,f(x)=6
6=ab
when x=2,f(x)=18
18=ab^2
