If someone could check me, that would be great!!

The finishing time for a runner completing the 200-meter dash is affected by the tail-wind speed, s. The change, t, in a runner's performance is modeled by the function shown below:

t= 0.0119s^2 - 0.308s - 0.0003

Predict the change in a runner's finishing time with a wind speed of 4 meters/second. Note: A negative answer means the runner finishes with a lower time.

Round to the nearest hundredth.

I got 1.042. Does this look correct?

actually, I recalculated and got: -1.0412. Which would round to -1.042, right?
