If f(x) = 1 - 2x^3, find the inverse of f.

1 answer:

7 0

Swap x and y's positions

f(x) is another way of saying y, so basically tha initial function is y = 1-2x^3.

Change it up to x = 1-2y^3 and solve for y

X - 1 = - 2y^3

(X - 1)/-2 = y^3

So the cube root of ((x-1)/2) = y

Answer:

More Than

Step-by-step explanation:

According to the given statement:

This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.

The two words in this problem which tell us about the operation are "More Than"

This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.

Since, x represents the earnings of last year, we can represent the earnings of this year as:

Twice of x + 20

2x + 20

Which sequence of transformations could be used to map triangle MNO onto M"N"O"? T(–2, 4) ry-axis ry-axisT(–2, 4) T(2, –4) T(2,

katrin [286]

Answer:

(A)T(–2, 4) ry-axis

Step-by-step explanation:

The graph showing triangles MNO and M"N"O" is attached below.

From the graph, the coordinates are:

M(5,-4),N(3,-2) and O(1,-3)

M"(-3,0), N"(-1,2) and O"(1,1)

When we <u>transform triangle MNO by (-2,4),</u> we obtain:

M'(3,0), N'(1,2) and O'(-1,1)

Next, we reflect M'N'O' the y-axis.

Note: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite.

Therefore:

Reflection of M'N'O' accross the y-axis gives: M"(-3,0), N"(-1,2) and O"(1,1).

Therefore, the sequence of transformations could be used to map triangle MNO onto M"N"O" is T(–2, 4) ry-axis.

The correct option is A.
