y-axis
That last sentence though, I died reading that.
Answer:
Step-by-step explanation:
logx
<=> logx + 2logy = a (1)
log
y=b <=> 3logx + 6logy =b (2)
(1),(2)=> logx= 
logy= 3a-b
=> log
=logy-logx=3a-b -(
) = 
log
=
(logx+logy)=........ OK
Answer:
2,7
Step-by-step explanation:
You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
