Question

F(x)=-x^2+3x+13 f(x)=−x 2 +3x+13 \text{Find }f(-10) Find f(−10)

Answer 1

The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.

How to find the value associated with a quadratic equation

In this case we have a quadratic equation (f(x) = - x² + 3 · x + 13) that has to be evaluated at a value of x, that is, x = 10. Now we proceed to show the solution of the exercise step by step:

- x² + 3 · x + 13, x = 10                   Given

- 10² + 3 · 10 + 13                           Previous step

- 100 + 30 + 13                              Definition of power / Definition of multiplication

- 57                                                Definition of addition and subtraction

The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.
