Answer :

A formula for H is given by H = 2/x+3 - x+3/2.

When x = -4, the value of H is -3/2 or -1.5.

To find the value of H when x = -4, we substitute -4 into the formula for H: H = 2/(-4+3) - (-4+3)/2. Simplifying the equation, we have H = 2/(-1) - (-1)/2, which further simplifies to -2 - (-1/2). Applying subtraction, we get -2 + 1/2. To add these fractions, we need a common denominator of 2. So, -2 is equivalent to -4/2. Combining the fractions, we have -4/2 + 1/2, resulting in -3/2. Thus, when x = -4, the value of H is -3/2 or -1.5. This indicates that H is equal to -1.5 when x is -4.
