Answer:
sorry but where is the triangle ️
Answer:
f^-1(x) is a function
Step-by-step explanation:
To get the inverse you replace f(x) with y, so you get y=3x^2+2. Then you switch your x and y to get x=3y^2+2. Now you want to solve for y, so you subtract two to get x-2=3y^2. You then divide both sides by 3 to get (x-2)/3=y^2. Finally you square root both sides to get y=√((x-2)/3). Now you get that f^-1(x)=√((x-2)/3). When you graph it you can see that the graph passes the vertical line test, so f^-1(x) is a function.
From the diagram, Vertex =(2,3)
So, (h,k)=(2,3)
So, h=2 and k=3
The equation of parabola is
p is the distance of directrix or focus from vertex.
As directrix is
y=8=k-p=3-p
So, 8=3-p
Let, us subtract 3 from both sides, we get
8-3=3-3-p
5=-p
or p=-5
So, h=2,k=3 and p=-5
So, the equation of parabola is
=4(-5)(y-3)
Equation of graph is
(x-2)^2=-20(y-3)
Answer:
<h2>
$20,000</h2>
Step-by-step explanation:
Step one:
we are told that the base salary is $24000
and also earns 8% of the total sale
let the total sales be x
additional earnings= 0.8x
the linear function for this situation is given as
y=0.8x+c
where y= the expected earning
x= sales
c= is the base salary
40000=0.8x+24000
solve for x
40000-24000=0.8x
16000=0.8x
divide both sides by 0.8
x=16000/0.8
x=20000
He needs to make sales of at least $20,000
