Give the range of the function f(x) = -x 2.

a. all reals
b. y ≤ 0
c. y ≥ 0

b. y ≤ 0

Step-by-step explanation:

Do you mean f(x) = -x^2?

If so, think of f(x) = x^2. You can use any real number for x. Once you square each value of x, you can get zero or a positive real for y. f(x) can only be a non-negative number. Now look at your function: f(x) = -x^2. The values of y are the opposite of the values of y in f(x) = x^2, so the range of f(x) = -x^2 is zero and all negative reals.

b. y ≤ 0

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

b. ol

step-by-step explanation:

i got the answer right on edg.

congruent: (geometry) (of figures) identical in form; coinciding exactly when superimposed.
