Elizabeth bought a new phone for $440 the store charge a 6% tax on the purchase

$466.4 is the total cost

Step-by-step explanation:

First, we need to find the tax

6% of 440 is __

Convert 6% into a decimal

0.06

Multiply

0.06 x 440 = 26.4

6% of 440 is 26.4

26.4 is the tax

Add 440 and 26.4

440+26.4=466.4

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer are
