let f(x)=7x+4 and g(x)= 3x-9
f(x)*g(x)
well, that would be
(7x+4)(3x-9)
1.2x
To find the product of f(x) and g(x), you need to multiply the two functions.
f(x) = 7x + 4
g(x) = 3x - 9
Now let's multiply f(x) and g(x):
f(x) * g(x) = (7x + 4) * (3x - 9)
To multiply these two expressions, we can use the distributive property or the FOIL method.
Using the distributive property, you multiply each term of the first expression by each term of the second expression:
(7x + 4) * (3x - 9)
= 7x * 3x + 7x * (-9) + 4 * 3x + 4 * (-9)
Multiply each term:
= 21x^2 - 63x + 12x - 36
Combine like terms:
= 21x^2 - 51x - 36
So, the product of f(x) and g(x) is 21x^2 - 51x - 36.
