True or false, a chi square curve starts at 0 on the horizontal axis and extends indefinitely to the left approaching but never touching the horizontal axis

Use Newton's method to find the slope of the tangent to the curve defined as y= 7x² + 4x - 10.

hi, can you help me with this whole question. thank you

An automobile, traveling at a constant rate, starts at home at time t = 0 and ends up 10 hours later 200 miles from home. It than changes speed and continues for the next 10 hours ending up 300 miles from home. It takes another 10 hours for it to return home. On two separate set of axes, sketch graphs of the distance and velocity functions.
