Select Function \( A, f(x)=3.3 x-4.7 \). Check the \( x_{1} \) info and \( x_{2} \) info boxes and use the \( x_{1} \)-slider and \( x_{2} \)-slider to set \( x_{1}=1 \) and \( x_{2}=2 \). Is it true or false that the function \( f(x)=3.3 x-4.7 \) must have a zero in the interval \( (1,2) \) ? Use the interactive figure to find your answer. Use the left and right arrow keys to move along a slider as needed. Click here to launch the interactive figure. Choose the correct answer below. True False
