State the possible number of real zeros for the function.

Question

x^3 +2x -3

State the possible number of real zeros for the function

Answer 1

Assuming the question is correct, you can use graphical method to find real zeros.

Then by using any graph plotter you can easy find al zeros as intersection points between the function's graph and x-axis. It will be at x=1.0

Answer 2

Assuming the question was x^2+2x-3

(x-1)(x+3) = 0 *factored and set equal to zero

x = 1 and x = -3 (these are the zeros of the quadratic function)
