Final answer:
To find the value of h(3) in the given function h(x) = -5x - 3h, substitute x = 3 into the equation and solve for h(3).
Step-by-step explanation:
The value of a function at a specific input, often denoted as f(x), represents the output or the dependent variable's value when the independent variable is set to a particular input value, denoted as x. In mathematical terms, it is written as f(x) or y when discussing the dependent variable.
To find the value of h(3) in the given function h(x) = -5x - 3h, we need to substitute x = 3 into the equation.
So, we have: h(3) = -5(3) - 3h.
Now, solve for h(3) by performing the arithmetic operations: h(3) = -15 - 3h.
