Answer:

Lower left.

Step-by-step explanation:

To determine if a graph is a function the "vertical line test is used. If any point on a graph has one x value go to two y values it is not a function.

Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values. So it must be the lower left one.

The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4. So this has two y values with one x value.

steposvetlana [31]

Answer:

The amount is $1480.24

Step-by-step explanation:

We are given

he puts $1000 in a savings account earning 4% annually after 10 years

so,

P=1000

r=4%=0.04

t=10

now, we can use formula

$A=P(1+r)^t$

now, we can plug values

$A=1000(1+0.04)^{10}$

$A=1480.24428$

So,

The amount is $1480.24
