Exercises 49-64: Complete the following: Find f(x) for the indicated values of x if possible: (b) Find the domain of f. Use words or inequalities to describe the interval f(x) = x^2 for 25 ≤ x ≤ 50. (f) f(x) = 2x - 1 for x = 5. (g) f(x) = -x^2 for x = -2. (h) f(x) = x^2 + 2 for x ≤ -2. (i) f(x) = -x^2 + 1 for x = -1, 4. (j) f(x) = |x - 3| for x = -1, 0. (k) f(x) = √(x + 2) for x = -1.

Step 1
f(x) = s+>-2 for -L This means that for any value of x less than or equal to -2, f(x) will be positive. So, we can write the domain of f as x ≤ -2 and the range of f as f(x) > -2. Show more…
