Question

What is f(x) = 0,5 (x-3)( x-5) in general form??​

Answer 1

`f(x)=0.5x^2-4x+7.5`

Explanation:

The general form of a quadratic function is:

`y=ax^2+bx+c`

We'll find the general form of the function:

`f(x)=0.5(x-3)(x-5)`

Multiplying the expressions in parentheses:

`f(x)=0.5(x^2-5x-3x+15)`

Simplifying:

`f(x)=0.5(x^2-8x+15)`

Operating:

`\mathbf{f(x)=0.5x^2-4x+7.5}`
