Graph of `y = f(x)` is as shown in the following figure. Find the roots of the following equations `f(x) = 0` `f(x) = 4` ` f(x) = x + 2` |
|
Answer» Correct Answer - (a) `x = -2 and x = 1` (b) `x = - 3 and x = 2` (c) `x = 2 and x = -2` Graphs of `y = f(x) ` intersect x-axis at x = -2 and x = 1, Which are roots of the equation `(x) = 0` (b) Graph of y = f(x) intersect the line y = 4 intersect at points whose x-value are - 3 and 2, which are the roots of the equation f(x) = 4 (c) For the roots of the equation f(x) = x + 2, we draw the graph of `y = x = 2`, which passes through the points (2, 4) and (-2, 0) which lies on the graph of y = f(x) also. so, roots of the equation f(x) = x + 2 are x = 2 and x = -2` |
