Find the inverse of the function y= -3/ x+ 4

The procedure for an inverse is to interchange x and y and solve for y

x = -3/y + 4 I'm solving this as it is written and not x = -3/(y + 4) Subtract 4
x - 4 = -3/y
y(x - 4) = - 3
y = -3/(x - 4)

If you did mean y = - 3/(x + 4) then the inverse would be
x = - 3 / (y + 4)
x*(y + 4) = -3
y + 4 = -3/x
y = -3/x + 4
Amazing! The inverse is the same as the original question.

Y=4-3/x
y-4=-3/x
(y-4)x=-3
x(y-4)=-3
x=-3/y-4

Find f(2) given f(x) = -3x^3 + x^2 – 3

aleksley [76]

Answer:

D

Step-by-step explanation:

f(x) = -3x^3 + x^2 – 3 f(2) means that wherever you see a x, put in a 2.

f(2)= -3(2)^3 + (2)^2 - 3

f(2) = -3*8 + 4 - 3

f(2) = - 24 + 1

f(2) = - 23

HELP ASAP 40 POINTS

AleksandrR [38]

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

$r=a_2-a_1$

$r=-12-(-8)$

$r=-12+8$

$r=-4$

The nth term of an AP is

$a_n=a+(n-1)d$

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

$a_n=-8+(n-1)(-4)$

$a_n=-8-4n+4$

$a_n=-4-4n$

Putting n=52, we get

$a_{52}=-4-4(52)$

$a_{52}=-4-208$

$a_{52}=-212$

Therefore, the equation for the nth term of the given sequence is $a_n=-4-4n$ and the 52nd term of the sequence is -212.
