First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
V=hpir²
h=4
d/2=r=15/2=7.5=r
V=4pi7.5²
V=4pi56.25
V=281.25pi
3.14=pi
V=706.7 ft³

Answer:
90
Step-by-step explanation:
we have:
9*(7-4)^2+9
we subtract 7 and 4: 7-4
we have:
9*(3)^2+9
we know: 3^2=3*3=9
so we have:
9*9 +9
we multiply 9 by 9: 9*9 = 81, so we have:
81+9
90
