A function is created to model the situation where the day of the month, x, is the independent variable, and the height of low tide, T, is the dependent variable. Plot the two points that we know on a graph. Include a dotted line representing the monthly average low tide height, and appropriately label the axes. Note that x = 1 is July 1.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

may i see the picture? it would a lot, xox

did you get the answer yet?
