Answer with explanation:

If an expression, f(x)=y, is a function, then for every y , there is unique x and for every x, there is unique y.

⇒f(3)=1, means ,when in the expression, x is substituted by, 3 , the value of y is 1.

⇒x(Domain)       y(Range)

  3                         1

The Set of values that x can take is called Domain of the function, and the set of values that y can take is called Range of the function.

The sum of a whole number and twice the square of the number is 10. Find the number.
sveticcg [70]

Answer:

x = \frac{10}{1 + 2x}

Step-by-step explanation:

Let the number be x

x + 2x² = 10

Factorize x + 2x²

x(1 + 2x) = 10

Divide both sides by (1 + 2x)

x = \frac{10}{1 + 2x}
