Question

HELP PLEASE ASAP

Answer 1

Answer: a) degree and sign

b) end behavior: left side → +∞, right side → -∞

c) x-intercepts: x = -1.3, 0.3, 1.0

Step-by-step explanation:

end behavior can be determined by two things:

1) the degree of the polynomial:

• if the degree is an even number, then the end behavior will be the same for both the left and right sides.
• if the degree is an odd number, then the end behavior will be different for both the left and right sides.

2) the sign of the leading coefficient:

• If the leading coefficient is positive, then the end behavior of the right side goes to positive infinity
• If the leading coefficient is negative, then the end behavior of the right side goes to negative infinity

W(x) = -5x³ + 7x - 2

Degree: 3 (odd)

Leading Coefficient: negative

So, end behavior is: right side goes to negative infinity, right side goes to positive infinity.
