The functions f(x)=√x^2+12x+36 and g(x)=x^3-12 are defined below. Which expression is equal to f(x) · g(x)? A.x^4-6x^3-12x+72 B.
Lostsunrise [7]

Answer:

C: x^4+6x^3-12x-72

Step-by-step explanation:

For the function : f(x)=√x^2+12x+36

It can be factorized to

f(x)=√(x+6)²

=x+6

f(x)*g(x)

=(x+6)(x^3-12)

Expand the brackets

=x^4-12x+6x^3-72

rearrange the numbers

x^4+6x^3-12x-72

3/10 as an equivalent fraction with a denominator of 100
viktelen [127]
30/100.

To get to this, you need to change the denominator to 100. 10 x 10 = 100 so whatever you do to the denominator, you do to the numerator. 3 x 10 = 30 so your answer would be 30/100.

What happens to a line when the y-intercept is changed? Check all that apply
Bond [772]
A and B
Reason and proof:
suppose we have the following function
f(x) = 2x + 1
the y intercept is 1 therefor it'll intersect the y axis at (0,1)
however if the function was to be
f(x) = 2x - 1
the y intercept is -1 that means it intersect the y axis at (0,-1)
