question 1.

- For function f

-the graph of y=f(x) extends down into quadrant lll and down into quadrant IV

-the zeros of f are -2,3 and 5

-the degree of f<5

1.what degrees is possible for f?

2.what are the maximum and minimum multiplicities possible for a zero of f?

3.two possible equations?

4.two possible graphs of y=f(x)

------------------------------------------------------------------------------------------------

question 2.

a.show that p(x)/x-a=Q(x)+R/x-a can be rearranged to p(x)=Q(x)(x-a)+R

b.evaluate p(a),showing it simplifies to R.

c.how does the answer in part b. relate to the remainder theorem?

d.using p(x)=Q(x)(x-a)+a to explain the factor theorem.(hint:what is the value of R if there is no remainder? substituted this value for R into Q(x)(x-a)+R to show x-ais a factor of p(x).

quastion 3

a cube with side length x has been modified by adjusting its side length x has been modified by adjusting its length, width and height. A student determined a function of the form v(x)=(x+a)(x+b)(x+c) can be used to represent the volume of the new box for different values of x, and then she graphed the function.

a.based on the graph ,predict how the side lengths of the original cube changed.(hint:what do the zeros of the function represent?

b.determine a polynomial function of the form v(x)=(x+a)(x+b)(x+c) that's matches the function in the graph .

c.which parts of the graph are realistic?(hint:all sides must be positive.using two negative side lengths to give positive volume is not realistic.)

In garden pea plants, tall stem height (T) is dominant over short stem height (t), and green pod colour (G) is dominant over yellow pod colour (g).

Some Genotypes of Pea Plants TTGG TTGg TTgg TtGG TtGg Ttgg ttGG ttGg ttggWhat number would be for the following? Correct me if I am wrong, please :)

*Pea plant used for a test cross: #3 is what I put, is that right?

Heterozygous tall and green pod pea plant #4 is what I put, is that right?

Yellow pod heterozygous tall pea plant #6

Just one more double check:

Which of the following statements correctly describes the Law of Independent Assortment?

Select one:

a. A large Punnett square can be used to predict the outcome of a parental cross involving two traits.

b. The dominant allele is represented with an uppercase letter and the recessive allele is represented with a lowercase letter.

c. Sometimes all alleles lack dominance, which leads to a blending of traits.

d. Non-allelic genes do not affect each other if they are located on separate chromosomes.

Is the answer not a?

In mice, black fur (B) is dominant over white fur (b).

A testcross was performed to determine the genotype of a black mouse. What is the genotype of the mouse that was test crossed with the unknown black mouse?

I put Bb, wouldn't it be bb for the other mouse?
