find the zero of 2x+3 graphically
Asked by imalakondarayudu1 | 30 Jan, 2024, 06:43: AM
Let f(x) = 2 x + 3
F(x) is calculated for various values of x and tabulated below
x | f(x) |
-2 | -1 |
-1 | 1 |
1 | 5 |
2 | 7 |
Above tabulated values are plotted so that f(x) is in y-axis
as seen from the graph y = f(x) = 0 when x = -1.5
Hence solution of the equation 2x+3 = 0 is x =-15
