Asap the change in the water level of a water tower is modeled by a polynomial function, w(x) = -5x3 + 7x - 2. which components of the equation relay information on the end behavior of the graph and describe the end behavior of the graph. describe how many x-intercepts of w(x) can be found and which components of the equation relays that information. using graphing technology find the approximate x-intercepts so that the city water department can predict when there will be no change in the water level

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:

2) the sign of the leading coefficient:

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.

See attachment for x-intercepts. I set the x-axis to represent tenths

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
