Question

Determine the range of the function. y = -2x2 + 3

Answer 1

\[y \le3\]

Answer 2

Thats incorrect. @tee.heeawesome

Answer 3

did u mean y=-2x^2+3?

Answer 4

if so, then:
y = -2x^2 + 3
y = -2(x + 0)^2 + 3
vertex is at (0, 3) and -2 < 0 so the answer is all real numbers less than or equal to three

Answer 5

uh, I'm sure that's cheating...
