Answer:
−(2x)/(5)−9
Step-by-step explanation:
Replace the function designators in g−1x
with the actual functions.
(3/5x−9)−1x
Simplify (3/5x−9)−1x
−(2x)/(5)−9
<span>It's 1/r!
nCr = n! / r!(n-r)!
nPr = n! / (n-r)!
If you divide the two you'd have:
n! / r! (n-r)! * (n-r)! / n! = 1/r!

Answer:
a) Vertex is at (-3, -1)
b) y-intercept is at (0,8)
c) x intercept is at (-4,0) and (-2,0)
d) x=-3
Step-by-step explanation:
We know the vertex is the lowest or highest part of a parabola meaning all the points are reflected across. It is the only y value without a matching pair
E.x. -1 and 1, -3 and 3
The only point without a corresponding y value is (-3,-1) therefore the vertex is at (-3,-1)
The y-intercept is where the parabola meets the y axis or the x value is equal to 0, we just have to find when x = 0 to find the y intercept
y intercept: (0,8)
For the x intercept's it is just the reverse, you need to find where the parabola crosses the x axis or when y = 0
x intercept 1:(-4,0)
x intercept 2: (-2,0)
The axis of symmetry is also the x coordinate of the vertex which is 3 so
x = 3
The solution to the problem about the possible values of x in the inequality is as follows:
4(x+15) >= 120
x+15 >= 30
<span>x >= 15
Therefore, there are </span><span>x >= 15 possibilities in the inequality.
