Graphing calculator turning point?

Question

College Algebra help:

The graph of the function has more than one turning point. Use your graphing calculator to find the coordinates of the turning point that lies in the given interval.

f(x)=4x^3-10x^2-x+5, [-1,0]

The coordinates of the turning point are _____

(Type an ordered pair. Type an integer or a decimal. Round each coordinate to the nearest hundreth if needed)

Can anyone give me the keystrokes on a TI-83+ calculator to get this answer???

Answer 1

In y = editor insert your equation

F2 zoom  (zoomstd or zoom fit)

F5 calc select min (and later max)

The calc will require left-bound;  arrow to left of TP you are finding then enter

The calc will then require right-bound;  arrow to right of TP you are finding then enter

Sure about the restricted domain, there is a max at x = 0
