Mike says the polynomial function fx=x4-2x3-3x2 has four unique zeros. Is he correct? Why or why not? AYes, Mike is correct. A fourth-degree polynomial has four unique zeros. B Yes, Mike is correct. The polynomial can be factored into a product of two monomials and two binomials of order 1. The four
unique zeros are the values that make each factor equal to 0.
No, Mike is not correct. The leading coefficient is one, not four, so there will not be four unique zeros.
D No, Mike is not correct. There are not four terms in the polynomial, so it cannot have four unique zeros.
E No, Mike is not correct. Two of the four factors are the same, so there are only three unique zeros.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
