Will mark brainliest given f(x) = x^4 - 2x^3 - 25x^2 + 26x + 120. explain how to find the x and y-intercept and end behavior without graphing technology. also, explain how to find the x & y-intercept and end behavior with graphing technology.

the end behavior is that it goes positive and both ends  (we look at x^4 ) and put in -inf and + inf and get +inf both times)

to get the y intercept let x=0  y intercept =120

to find the x intercepts we factor  and find the zeros

using graphing technology  we plot the function

we look at the ends  of the graph if it goes down it goes to - inf, if it goes up it goes to + inf

the y intercept is where x=0

there x intercepts are where it crosses the x axis on the plot (there should be 4 unless some are imaginary)

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
