Answer:
f(x)=19(2)^x
Standard form of exponential graph is f(x) = ab^x
Plugging in (0, 19), you get
19 = ab^0 -> 19 = a(1)
a=19
f(x)=19b^x
1216 = 19(b)^6
64=b^6
b=2
-> f(x) = 19(2)^x
Answer:
Exact form : x = +_2 squareroot 11+5
Decimal form : x=11.63324958...,-1.63324958...
Step-by-step explanation: Use the formula (b/2)^2 in order to create a new term. Solve for x by using the term to complete the square.
I hope this helps you out! :)
