The y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)
Given the polynomial function 4x^3-3x^2+7, the y-intercept of the function occurs where the value of x is zero
Substituting x = 0 into the polynomial function will give;
y = 4x^3-3x^2+7
y = 4(0)^3-3(0)^2+7
y = 0 - 0 + 7
y = 7
Hence the y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)

Volume of Sphere
The volume of sphere is 904.32 cm³
Step-by-step explanation:
Sphere is a geometrical object in three dimensional space (like the surface of a ball). Every point on its surface of a sphere equidistant from its center.
Circle is a two dimensional figure where as sphere is a three dimensional figure.
The volume of the sphere is defined as 
where r is radius of the sphere
V = 
Given radius r = 6 cm

V = (4/3) × 3.14 × 6³
= (4/3) × 3.14 × 216
= 904.32 cm³
Hence the Volume of the sphere is 904.32 cm³
