Increasing & Decreasing Functions

For all x in the given interval , if f'(x)>0, then f(x) is

• increasing in the interval
• decreasing in the interval
• constant in the interval
• Undefined in the interval

For all x in the given interval, if f'(x)<0, then f(x) is

• increasing in the interval
• decreasing in the interval
• constant in the interval
• Undefined in the interval

Find the range of values of x for which the function is increasingy = 5-8x-2x^2

• x< 3
• x>2
• x< -2
• x> -2

A function can have points at which the function is increasing, decreasing or constant

• True
• False
• Not possible
• information is incomplete

Find the values of x for which the function is decreasing

• -2<x<3
• -2<x<0
• 1/2 <x<3
