If a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1, what will be the resulting three - dimensional
object.
Cone
Cylinder
Sphere
Pyramid

the answer is 45 i just did it on oddesy ware

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy
