Answer:
f(x) = 2x +1
Step-by-step explanation:
Apparently the ordered pairs are ...
(x, f(x)) = (1, 3), (2, 5), (3, 7), (4, 9)
We note that as x increases by 1, the value of f(x) increases by 2. The difference between f(x) and 2x is 3-2·1 = 1, so we have ...
f(x) -2x = 1
f(x) = 2x +1 . . . . . . add 2x
Answer:
3
Step-by-step explanation:
f(x)=a*b^x - is a formula of exponential function
As we know the point (x=0; y=3) lies at the function's graph.
So we have to put in formula f(x)=a*b^x x=0 f(x)=y=3
3=a*b^0 (b^0=1) => 3=a*1 => 3=a

Answer:
It is neither linear nor exponential.
Step-by-step explanation:
x values: −10,−3, 4, 11
y values: 1, 6, 30, 120
Slope = rate of change


Since rate of change is not constant . So, It is not linear
If the average rate of change is constant, then the function is linear.
If the ratio of consecutive outputs is constant, then the function is exponential.
So, 
Since the ratio of consecutive outputs is not constant.
So, It is not exponential
Hence it is neither linear nor exponential.
Answer:
The answer is 88.
Step-by-step explanation:
68+81+74+89+x/5=80
312+x/5=80
312+x=80*5
312+x=400
x=400-312
x=88
