Determine whether f(x) is continuous at x = 1. If discontinuous, identify the type of discontinuity as infinite, jump, or removable.
Ax)={x^2 + 1 if x < 1
{-x^3+2 if x>1
Select all that apply.
A The function is discontinuous at x =1.
B. The function is continuous at x =1.
C. Infinite Discontinuity
D. Jump Discontinuity
E Removable Discontinuity

x-3y=4

step-by-step e

answer is 1

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
