Decide if each of the following functions is a polynomial function. If it is, state the degree. If it is not, explain how you know. Homework Help ✎
f(x) = 3x3 – 2x + 5
y = 0.25x7 – 5x
y = 3x – x2
f(x) = x2 –
Q(x) = 3(x – 4)2(x + 2)
y = x2 – 3x + 5 –
Review the Math Notes boxes in Lessons 1.1.4 and 8.1.1.
Yes; degree 7
No; it contains an exponent of x.
The expoenents must be whole numbers. What is the exponent of a square root?
If you were to expand and simplify, what would be the highest power of x?
