1. What is (f⋅g)(x)?

nekit [7.7K]

Answer:

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$

Step-by-step explanation:

For the first part of the question we have two functions

$f(x) = x^4 -9$

$g(x) = x^3 + 9$

If the expression refers to the multiplication of f and g, then:

(f⋅g)(x) $= f (x)g(x)$

So we multiply the function f(x) with the function g(x)

(f⋅g)(x) $= (x^4 - 9)(x^3 + 9)$

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

For the second part we have the functions:

$f(x) = x^3 -2x^2 + 12x - 6\\\\g(x) = 4x^2 - 6x + 4$

We wish to find (f - g) (x). We know that

$(f - g)(x) = f(x) - g(x)\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 - [4x^2 - 6x + 4]\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 -4x^2 + 6x - 4$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$

The function f(x) = 2x − 1 is transformed to function g through a horizontal shift of 7 units left. What is the equation of func

Softa [21]

Answer:

h = 7, k = -1

Step-by-step explanation:

After 7 units left,

The function f(x) maps onto f(x+7)

g(x) = f(x + 7)

g(x) = 2(x + 7) - 1

g(x) = 2(x + h) + k

h = 7, k = -1
