Use the upper bound theorem to find the least integral upper bound and the greatest integral lower bound of the zeros of each function. 5. f(x) = 2x3 – x2+x-6 6. f(x) = x4 + x2 – 3 7. f(x) = x3 + 3x + 7 NEED HELP ASAP FOR THIS PLEASE

true !

step-by-step explanation:

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
