Let x = diameter
x=2160 x (1/150)
x=2160/150
x=14.4
Diameter of the model is 14.4.
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
