Change all the signs. Suppose you have the quadratic equation: y = ax2 + bx + c Its additive inverse is -ax2 - bx - c.
fx=5x1 / 9

f(x) = bX is not an exponential function so the question makes no sense.
If the quadratic function is f(x) = ax^2 + bx + c then its inverse isf'(x) = [-b + +/- sqrt{b^2 - 4*(c - x)}]/(2a)
y=x
in general, the y-intercept of the function f(X)= axb^x is the point__.
The logarithm function. If y = bx, then x = by is the inverse --> y = logb(x). If b = 10, then the function is often stated with the '10' implied: just log(x). For natural logarithms (y = ex), the function y = ln(x) [which indicates loge(x)] is the inverse.

To find the inverse of a matrix on a Casio fx-991MS scientific calculator, you first need to input the matrix you want to find the inverse of. Then, press the "SHIFT" button followed by the "MODE" button to access the matrix mode. Select the matrix you want to invert by pressing the corresponding number key. Next, press the "SHIFT" button followed by the "MATRIX" button, and then press the "x^-1" button to calculate the inverse of the matrix.

Depending on the domain and range, the inverse may or may not be defined. Assuming it is defined, the inverse function can be derived as follows: The negative parabola is y = -ax2 + bx + c (where a>0) so that -ax2 + bx + c - y = 0 using the quadratic formula, x = [-b ± sqrt(b2 + 4*a*(c-y)]/(-2a) which is a square root function, and will be real provided that b2 + 4*a*(c-y) > 0
