Question 136855
To do any of these, you need to understand what k(0) and k(-15) mean.

You are given a function {{{ k(x) = x + 16}}} and then asked to evaluate that function at specific values for x.

For instance, k(0) means "the value of the function when x = 0"
{{{ k(x) = x + 16}}}  Sub in 0 for every x in the function
{{{ k(0) = 0 + 16}}} 
{{{ k(0) = 16}}} read that as "k of 0 equals 16"

Do the same steps for k(-15)
{{{ k(x) = x + 16}}}
{{{ k(-15) = -15 + 16 }}}
{{{ k(-15) = 1 }}}  read "k of negative 15 equals 1"
