30 points! below are two different functions, f(x) and g(x). what can be determined about their y-intercepts?
1) the function f(x) has a higher y-intercept.
2) the relationship between y-intercepts cannot be determined.
3) the function g(x) has a higher y-intercept.
4) they both have the same y-intercept.

A) The function f(x) has a higher y-intercept.

Step-by-step explanation:

If we look at the chart we look at it and can use the process of elimination. We look at the first one and say ok, than the second-fourth and see they can't be so it must be the first.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
