Question

Question 3 of 10 Which point is on the graph of f(x) = 3.4*? O A. (0,0) O B. (1, 12) O C. (12, 1) D. (0,12)

Answer 1

the given expression is

`f(x)=3*4^x`

we will check for all four points

by putting their values,

for point A (0,0)

put x = 0

`\begin{gathered} f(x)=3*4^0 \\ f(x)=3 \end{gathered}`

for x = 0 we have y or f(x) = 3 so point A(0,0) is not satifying the equation

for point B(1,12)

put x = 1

`\begin{gathered} f(x)=3*4^1 \\ f(x)=12 \end{gathered}`

for x = 1 we have y or f(x) = 12

so it is satisfying the equation,

thus the correct answer is option B
