How do you find the domain and range of #f(x)= -2 + sqrt(16 - x^2)#?
Find the highest and lowest x-values for which the function is defined, then find the highest y-value (which will occur at
Look for where the function is defined. Recall that we cannot take the square root of a negative number; thus, for all x,
Thus, this function is only defined for
Thus, our range will be
