Question

Help!! Find the value of f(3)

Answer 1

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
