Question

which ordered pair lies on the graph of the exponential equation f (x) =25 (2.2)x (0,0) (0.5 37.08) (1, 55) (2,121)

Answer 1

`\begin{gathered} f(x)=25(2.2)^x \\ \text{For x=0} \\ f(0)=25\cdot1=25\\e0 \\ \text{For x=0.5} \\ f(0.5)=25\cdot2.2^(0.5)=37.08=37.08 \\ \text{For x=1} \\ f(1)=25\cdot2.2=55 \\ \text{for x=2} \\ f(2)=25\cdot4.84=121 \end{gathered}`

Correct answers:

(0.5 37.08)

(1, 55)

(2,121) ​
