You find how y and x change and then divide y/x to get your rate of change
The answer is gonna be Parabola for sure
Answer:
y=3x+7
Step-by-step explanation:
y=mx+c
m=3 parallel lines have the same gradient
(-2,1)
(x,y)
y=mx+C
1=3x-2+c
1=-6+c
c=7
y=3x+7
Unsure of whether this is a composite function or not. It does look like you've multiplied f(x) and g(x) together.
Looking at <span>-30x2 - 9x + 12, we see immediately that this is a polynomial function. Because of that, the domain is the set of all real numbers. The graph of this poly opens down, so the max value is at the vertex, x = -b / (2a).
Here a= -6 and b= -9, so this x-value is -(-9) / (2*(-6)), or x = 9/12, or x = 3/4.
By subst. 3/4 for x in the poly., we find that the max y value is 4.83. Thus,the rante is (-infinity, 4.83].</span>
