Answer 2

Function Example

A function can be represented by the formula f(x) = x^2 + 3x - 5. This means that for any given value of x, the function will output a value calculated using the formula x^2 + 3x - 5.

For example, if we want to find the value of the function at x = 2, we can substitute x = 2 into the formula: f(2) = 2^2 + 3*2 - 5 = 4 + 6 - 5 = 5.

So, for the given function f(x) = x^2 + 3x - 5, when x is 2, the value of the function is 5.

Explanation of the Function

The function f(x) = x^2 + 3x - 5 represents a quadratic function, where the highest degree of the variable x is 2. This means the graph of this function will be a parabola.

The coefficients in the formula affect the shape and position of the parabola. For example, the coefficient of x^2 (which is 1 in this case) determines the "width" of the parabola, while the coefficient of x (which is 3 in this case) affects the position of the vertex of the parabola.

The constant term (-5 in this case) shifts the entire graph up or down along the y-axis.

Conclusion

In summary, the function f(x) = x^2 + 3x - 5 represents a quadratic function, and by substituting different values of x into the formula, we can calculate the corresponding values of the function.
