f(0) = 0

f(70) = 16.74

f(58.5) = 15.30

$x \geq 0$

Step-by-step explanation:

Given

$f(x) = 2\sqrt x$

Solving (a): f(0)

$f(x) = 2\sqrt x$

$f(0) = 2 * \sqrt 0$

f(0) = 2 * 0

f(0) = 0

Interpretation:

This implies that, the cost of 0 paints is $0

Solving (b): f(70)

$f(x) = 2\sqrt x$

$f(70) = 2 * \sqrt{70$

f(70) = 2 * 8.37

f(70) = 16.74

Interpretation:

This implies that, the cost of 70 paints is $16.74

Solving (c): f(58.5)

$f(x) = 2\sqrt x$

$f(58.5) = 2 * \sqrt{58.5$

f(58.5) = 2 * 7.65

f(58.5) = 15.30

Interpretation:

This implies that, the cost of 58.5 paints is $15.30

Solving (d): The domain

$f(x) = 2\sqrt x$

Set the radicand x to $\geq 0$

i.e.

$x \geq 0$

Hence:

The domain is $x \geq 0$
