Final Answer:

The correct formula for the function
\( h \) is b) \( h(x) = -3x - 2 \).

Explanation:

In the given options, the correct formula is identified by analyzing the structure and coefficients of the function. The correct formula follows the general form
\( h(x) = mx + b \) where
\( m \) is the slope (coefficient of x and b is the y-intercept (constant term).

Let's break down each option:

a)
\( h(x) = -3x - 2 - 1 \): This option has an additional constant term (-1) which is not present in the standard form.

b)
\( h(x) = -3x - 2 \): This option matches the standard form with a slope of -3 and a y-intercept of -2.

c)
\( h(x) = -3x^2 - 1 \): This option includes a squared term
(\( x^2 \)), indicating a quadratic function, whereas we are looking for a linear function.

d)
\( h(x) = -3x^2 + 1 \): Similar to option c, this is a quadratic function with a squared term.

By comparing the options with the standard form of a linear function,
\( h(x) = mx + b \) option b is the correct formula for the given function h . It has the appropriate coefficients for a linear equation, making it the accurate representation of the function.
