3. 1 The greatest exponent of an even-degree function is even. Examples of even-degree functions include y = 3x?, y = x* - 5x3 + 8, and y = 2x3 + x5 - x. In the Gizmo, experiment with functions of degree 2 and 4. A. Fill in the blanks to show what happens to y as x approaches infinity or negative infinity when the leading coefficient of an even-degree function is positive. as x -> co, y-> as x -> -00, y-> B. Fill in the blanks to show what happens to y as x approaches infinity or negative infinity when the leading coefficient of an even-degree function is negative. as X -> co, y -> as X -> -oo, y ->
