Jun 10, 2016 · Explanation: When we have a question that gives a function, such as f (x) = 2x2 and we are then asked what that function would then be with f (2x), we substitute the 2x in for every x we see. Like this: f (2x) = 2(2x)2. We can now simplify it: f (2x) = 2(4x2) f (2x) = 8x2. Answer link.

Evaluating Functions. To evaluate a function is to: Replace ( substitute) any variable with its given number or expression. Like in this example: Example: evaluate the function f (x) = 2x+4 for x=5. Just replace the variable "x" with "5": f ( 5) = 2× 5 + 4 = 14. Answer: f (5) = 14.
Quadratic polynomial can be factored using the transformation ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right), where x_{1} and x_{2} are the solutions of the quadratic equation ax^{2}+bx+c=0. x=\frac{-\left(-3\right)±\sqrt{\left(-3\right)^{2}-4\times 2\left(-2\right)}}{2\times 2}
