Consider the function ƒ(x) = –x4 + 9. Determine which of the following is its graph, based on end behavior.
1 answer:
Answer:
Step-by-step explanation:
If the degree of the polynomial is even (positive) ends of the function will either upwards or downwards on axis.
If the coefficient of the leading term of a polynomial is negative, both the ends of the graph will move downwards.
The given function is,
f(x) = -x⁴ + 9
Degree of the polynomial = 4
Coefficient of the leading term = -1
Therefore, ends of the polynomial will open downwards.

Answer:
WX = 7.9
Step-by-step explanation:
By applying tangent rule (law of tan) in the given right triangle WXY.
tan(W) =
tan(27)° =
0.509525 =
WX =
WX = 7.85
WX ≈ 7.9
Therefore, length of side WX is 7.9 units.
