Me ‼️
the function d(h)= 25h+50 models the distance a train traveled from a station , in miles , h hours after crossing a bridge . what is the meaning of the x-intercept ?
a. train cross the bridge two hours after leaving the station
b. the train station is located 2 miles from the bridge
c. the train station is 50 miles from the bridge
d. the train crossed a bridge every 50 miles

We know that the value of x, the independent variable, is 0 at the x-intercept. In this case, time is the independent variable as distance traveled is dependent on it. Therefore, when time is equals to 0, we find that the distance was 50 miles. If the distance is being measured from the bridge, and the train is at the station at time = 0, then the train station is 50 miles from the bridge.

Xis equal to three
