How do i solve this? :

7-12÷4+2x7

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.
