Question

How do I find the value of f(-1) if f(x) = 7 squared + 2x +14?

Donagan

Top Answerer

Substitute (-1) for each x in the expression. You have written f(x) = 7² + 2x + 14. That simplifies to 2x + 63. Substituting (-1) for x makes f(-1) = (-2) + 63 = 61. If you meant to write that f(x) = 7x² + 2x + 14, then f(-1) = 7(-1)² + 2(-1) + 14 = 7 - 2 + 14 = 19.

Question

What if it is a whole number and a fraction like 4 1/4?

Community Answer

It doesn't matter. The absolute value of any number -- a whole number, a fraction, a mixed number, a number with a decimal -- is that number. The absolute value of x is x. (If the number is negative, the absolute value is the positive version of that number. The absolute value of -x is x.)
