Find a third degree polynomial with rational coefficients that has the given numbers as given roots 4 and 3 -

Step-by-step explanation:

Since we are looking for a polynomial with RATIONAL coefficients, then we know that if  is a root, then its conjugate   must also be a root

Therefore, we build the polynomial using binomial factors with the given roots as shown below:

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
