Answer:
9-x
Step-by-step explanation:
Hope i understand it right
9y^2 -12y^4 = 3y^2 *(3 - 4y^2)
Yes because they both have the same degrees, but one is slightly rotated
Answer:
(a) Domain: x > 4
(b) Range: y < -2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted by function f(x).
We see that our x-values span from 4 to infinity. Since it is an open dot, we cannot include it in our domain:
(-4, ∞)
We also see that our y-values span from -2 to negative infinity. Since it is an open dot, we cannot include it in our range:
(-∞, -2)
