x - 3 is a factor of P(x) = x^3 – 7x² +15x-9
A. True
B. False

Answers

A. True
Explanation-

Let p(x) = x^3 – 7x^2 – 15x – 9

For checking that (x – 3) is a factor of p(x), we find : p(3)

p(3) = (3)^3 – 7(3)^2 + 15(3) – 9

= 27 – 63 + 45 – 9

= 72 – 72

= 0

Hence, (x – 3) is a factor of p(x).

By division of p(x) by x – 3, we get the quotient

= x^2 – 4x + 3

∴ x^3 – 7x^2 + 15x – 9

= (x – 3)(x^2 – 4x + 3)

= (x – 3)(x – 3)(x – 1)

= (x – 3)^2(x – 1)

Step-by-step explanation:

Identify the maximum or minimum value and the domain and range of the graph of the function y = 2(x – 3)2 – 4. a. minimum value: –4
domain: all real numbers
range: all real numbers –4

b. maximum value: 4
domain: all real numbers
range: all real numbers 4

c. maximum value: –4
domain: all real numbers –4
range: all real numbers

d. minimum value: 4
domain: all real numbers4
range: all real numbers

Answers

we are given the equation y = 2(x – 3)^2 – 4 and is asked for the domain and range of the following function. In this case, there is no radical sign so the domain includes all real numbers. The range has a minimum value of -4 since the squaring makes the value on the first term positive. Hence the answer is A. 

Answer:

a. minimum value: –4

domain: all real numbers

range: all real numbers –4
