A.
Approximate the real zeros of f(x) = 3x + x2 - 1 to the nearest tenth
A. -0.7,0.7
B. -7,7
b. -0.5, 0.5
d. -0.6, 0.6
Please select the best answer from the choices provided.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
