A fixed point of f is a value of x that satisfies the equation f(x) = x; it corresponds to a point at which the graph of f intersects the line y = x. Find all the fixed points of the function. Use preliminary analysis and graphing to determine good initial approximations. Round approximations to six decimal places.f(x) = x2 - 3
A. x ? -1.302776, 2.302776 B. x ? -0.802776, 1.802776 C. x ? -2.302776, 3.302776 D. x ? -1.802776, 1.802776

Use inductive reasoning to predict the next equation.36 - 34 + 32 - 30 = 37 - 35 + 33 - 3146 - 44 + 42 - 40 = 47 - 45 + 43 - 41
A. 56 - 54 + 52 - 50 = 57 - 55 + 53 - 51 B. 56 + 54 - 52 - 50 = 57 + 55 - 53 + 51 C. 56 - 54 - 52 + 50 = 57 - 55 + 53 - 51 D. 56 + 54 - 52 + 50 = 57 + 55 - 53 + 51
