Question

The equation 4x + 2 has a domain of {0,3,6), what is the range

Answer 1

Explanation

• Domain and Range

Domain is basically an input while Range is an output. Domain is the set of all x-values while Range is the set of y-values.

$\large \boxed {domain} = > \large \boxed{range}$

From input to output. That means from if we substitute domain in the equation, we would get range.

• Substitute x = 0,3 and 6 in the equation.

$f(x) = 4x + 2 \\ f(0) = 4(0) + 2 = 0 + 2 = 2 \\ f(3) = 4(3) + 2 = 12 + 2 = 14 \\ f(6) = 4(6) + 2 = 24 + 2 = 26$

We input the value of x that are given and we get the value of f(x) which is the output at the specified domain.

Answer

• Range

$\large \boxed{2, 14, 26}$
