Use the intermediate value theorem to show that the polynomial f(x)= x + 2x - 6 has a real zero on the interval [1,2]
Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice.
O A. The polynomial has a real zero on the given interval, because f(1) = and f(2)= are both negative
OB. The polynomial has a real zero on the given interval, because f(-x) has variation(s) in sign
OC. The polynomial has a real zero on the given interval, because f(1) = and f(2) are complex conjugates.
OD. The polynomial has a real zero on the given interval, because f(1) = and f(2)= are outside of the interval
O E. The polynomial has a real zero on the given interval, because f(1) = and f(2)= are opposite in sign
OF. The polynomial has a real pero on the given interval, because f(1) = and f(2)= are both positive

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
