Let f(x) = -2x + 7 and g(x) = -6x + 3. Find fxg and state its domain.

-14x^2 + 36x - 18; all real numbers except x = 7

-14x^2 + 36x - 18; all real numbers

12x^2 - 48x + 21; all real numbers except x = 1

12x^2 - 48x + 21; all real numbers

Option D: ; all real numbers.

Explanation:

Given that the functions are and

We need to determine the value of and its domain.

The value of :

The value of can be determined by multiplying the two functions.

Thus, we have,

Thus, the value of is

Domain:

We need to determine the domain of the function

The domain of the function is the set of all independent x - values for which the function is real and well defined.

Thus, the function has no undefined constraints, the function is well defined for all real numbers.

Hence, Option D is the correct answer.

12x² - 48x + 21; all real numbers

Step-by-step explanation:

f(x) = -2x + 7

g(x) = -6x + 3

f(x)×g(x) = (-2x + 7)(-6x + 3)

= 12x² - 42x - 6x + 21

= 12x² - 48x + 21

step-by-step explanation:

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
