What is the value of the function y=3x−1 when x =−1 ? −8 −4 2 6

1 answer:

8 0

So check my calculations,
Plug in -1 into the first equation as x
y= 3(-1)-1
y=-3-1
y=-4
Hope I helped! Do not hesitate to ask any questions :)

ANSWER

$f( - 1) = 2$

EXPLANATION

The given function is a piecewise defined function.

$f( - 1)$
is the y-value that corresponds to
$x = - 1.$

To determine that y-value, we need to trace from
$x = - 1$
to where it meets the graph.

We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.

From the graph, we can see that this x-value corresponds to a y-value of
$2$

This implies that, when
$x = - 1,y = 2$

Therefore
$f( - 1) = 2$
See graph.
