Discuss the continuity of the function f given by f(x) = |x - 1| + |x - 2| at ..

In the first quadrant, as x approaches zero from the right of zero, the value of f(x) increases without bound. It becomes greater than any assigned positive real value. In this case, we say or Similarly, in the third quadrant as x approaches zero from the left, the value of decreases witho..

For the function f(x) = x+ (x-[x]) 2 , find the RHL and LHL at x = 2. Check whethe..

2x + 3y = 5, x - 2y = 6, -6x + y =8 A pair of values of x and y that satisfy a given linear equation in two variables is said to be its soluti..

2x+3=4 Coordinates The co-ordinate of the foot of the perpendicular draw on the x-axis from the given point P is x-coordinate of the point P ('a'). Similarly 'b' is the y-coordinate of the point P. The coordinate of P are (a, b). The ordered pair of the coordinates (a, b) denotes t..

i) 3x + 5 = 8, is satisfied by the value of x = 1. ii) x 2 - 4 = 0, is satisfied by the value of x = 2 or x = ..
