If `f^(prime)(x)=|[mx, mx-p, m x+p], [n, n+p, n-p], [mx+2n, m x+2n+p, mx+2n-p]|` , then `y=f(x)` represents a. a straight line parallel to x-axis b. a straight line parallel to y-axis c. parabola d. a straight line with negative slope

A

a straight line parallet to x-axis

B

a striaght line parallel to y-axis

C

parabola

D

a striaght line with negative slope

Text Solution

Verified by Experts

The correct Answer is:
B
`R_(3) to R_(3)- 2R_(2)` hence two indentical rows `rArr f(x) =` constant
