Question 1
1 / -0

If the graph of a differentiable function y = f (x) meets the lines y = – 1 and y = 1, then the graph

A
meets the line y = 0 at least twice

B
meets the line y = 0 at least thrice

C
meets the line y = 0 at least once

D
does not meet the line y = 0.

Solution

Explanation:

Since the graph cuts the lines y = -1 and y = 1 , therefore ,it must cut y = 0 atleast once as the graph is a continuous curve in this case.
Question 2
1 / -0

In case of strict decreasing functions, slope of tangent and hence derivative is

A
Positive

B
either negative or zero.

C
Zero

D
Negative

Solution

Explanation:

In case of a strict decreasing function , slope of tangent and hence derivative is either negative or zero because decreasing function change sign from positive to negative and making obtuse angle measured clockwise.Hence negative and will be zero at peak.
