Many questions get answered in a day or so. I don't see an x minus 3/2 here, but as we've mentioned in other videos you can also multiply So for example, from left to right, how do we know that the graph is going to be generally decreasing? Select one: Let's look at the graph of a function that has the same zeros, but different multiplicities. At x= 2, the graph bounces off the x-axis at the intercept suggesting the corresponding factor of the polynomial will be second degree (quadratic). If a polynomial of lowest degree phas zeros at [latex]x={x}_{1},{x}_{2},\dots ,{x}_{n}[/latex],then the polynomial can be written in the factored form: [latex]f\left(x\right)=a{\left(x-{x}_{1}\right)}^{{p}_{1}}{\left(x-{x}_{2}\right)}^{{p}_{2}}\cdots {\left(x-{x}_{n}\right)}^{{p}_{n}}[/latex]where the powers [latex]{p}_{i}[/latex]on each factor can be determined by the behavior of the graph at the corresponding intercept, and the stretch factor acan be determined given a value of the function other than the x-intercept. The revenue in millions of dollars for a fictional cable company from 2006 through 2013 is shown in the table below. 1 has multiplicity 3, and -2 has multiplicity 2. Use k if your leading coefficient is positive and -k if your leading coefficient is negative.

For general polynomials, finding these turning points is not possible without more advanced techniques from calculus. WebWrite an equation for the function graphed below Hence f(x) = 12(x - 1)/[(x + 2)(x - 3)] is the equation of the function graphed as in the figure. That refers to the output of functions p, just like f(x) is the output of function f. Function p takes in an input of x, and then does something to it to create p(x). You can find the correct answer just by thinking about the zeros, and how the graph behaves around them (does it touch the x-axis or cross it). If a term has multiplicity more than one, it "takes away" for lack of a better term, one or more of the 0s. And you could test that out, two x minus three is equal to Thanks! If you use the right syntax, it meets most requirements for a level maths. The infinity symbol throws me off and I don't think I was ever taught the formula with an infinity symbol.

How to find 4th degree polynomial equation from given points? The polynomial remainder theorem states that if any given function f(x) is divided by a polynomial of the form (x - a), f(a) = the remainder of the polynomial division. Mathematics can be a daunting subject for many students, but with a little practice, it can be easy to clear up any mathematic tasks. On the graph of a function, the roots are the values of x for which it crosses the x-axis, hence they are given as follows: When x = 0, y = -3, hence the leading coefficient a is found as follows: More can be learned about the Factor Theorem at brainly.com/question/24380382, This site is using cookies under cookie policy .
