Answer:
Step-by-step explanation:
Start with where it tells you the value of x. The value of x is 3. That's given by f(x) = f(3)
Next see which one of the functions you use. x > 0 is given by x^4 - 7. Since 3 is greater than zero you use x^4 - 7
f(3) means that wherever you see an x on the right side, you put a 3.
f(x) = x^4 - 7
f(3) = 3^4 - 7
f(3) = 81 - 7
f(3) = 74
Answer:
the answer wold be 10.129
Step-by-step explanation:
To solve for m;
39 = 3m -12
39+12 = 3m -12 + 12 (add 12 to both sides)
51 = 3m
51 ÷ 3 = m
17 =m
m =17
