We need to find 3 numbers that sum up to 34.
There are infinite number of possibilities.

From these combinations:
4+20+10 = 34
3+22+9 = 34
15+15+4 = 34
15+10+9 = 34
30+4+0 = 34
10+10+14 = 34

I'll help with a few.

3. -3x^3 - 9x^2 + 3x
Solve:
= (-3x)(x^2 + 3x + -1)
= (-3x)(x^2)+(-3x)(3x)+(-3x)(-1)
= -3x^3 - 9x^2 + 3x

7. (m - 2) (m + 11)

8. (t - 2) (5t + 9)

9. (5x + 3) (5x - 3)

10. (3t + 2)^2

If f(x) = log2(x+4), what is f-1(3)

svp [43]

Imma just solve for f⁻¹(x) for this one

to solve fr the invers
replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

I'm assuming your thing is $f(x)=log_2(x+4)$

remember

$log_a(b)=c$ translates to $a^c=b$

so
if we replace y with f(x)
$y=log_2(x+4)$
switch
$x=log_2(y+4)$
translate
$2^x=y+4$
minus 4
$2^x-4=y$
$f^{-1}(x)=2^x-4$
evaluate
$f^{-1}(3)=2^3-4$
$f^{-1}(3)=8-4$
$[f^{-1}(3)=4$

it equals 4

When finding the bottom numbers, divide the top number by 3

when finding the top numbers,
multiply the bottom number by 3

21 / 3 = 7
12 X 3 = 36
20 X 3 = 60
90 / 3 = 30
