If f (x) = 2x-3 and g (x) = 4x+5, what is (f⋅g) (x) ?

(f⋅g) (x) = 8x^2-2x-15

(f⋅g) (x) = 6x+2

(f⋅g) (x) = 8x^2+22x-15

(f⋅g) (x) = 8x-15

(f⋅g) (x) = 8x^2-2x-15

Step-by-step explanation:

To find the expression (f*g) (x), multiply f (x) into g (x) using the distribution property.

(f*g) (x) = (2x - 3) (4x + 5) = 8x² - 12x + 10x - 15 = 8x² - 2x - 15

If f (x) = 2x-3 and g (x) = 4x+5, what is (f⋅g) (x) ?(f⋅g) (x) = 8x^2-2x-15(f⋅g) (x) = 6x+2(f⋅g) (x) = 8x^2+22x-15(f⋅g) (x) = 8x-15

If f (x) = 2x-3 and g (x) = 4x+5, what is (f⋅g) (x) ?

(f⋅g) (x) = 8x^2-2x-15

(f⋅g) (x) = 6x+2

(f⋅g) (x) = 8x^2+22x-15

(f⋅g) (x) = 8x-15
