Answer:
4 3/5
Step-by-step explanation:
Convert each term into an improper fraction, 8/5 x 15/8. Then find common denominator, 40. Then your equasion would be 64/40 x 75/40. Multiply your terms, then simplify the answer.
The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
Answer:
log2(0.25) = -2
512 = 8^3
Step-by-step explanation:
- <em>Use of formula: </em><em>loga (b) = c ⇔ b = a^c</em>
Rewrite the following equation in logarithmic form.
0.25 = 2^-2
Rewrite the following equation in exponential form. log8 (512) = 3
