Question

Evaluate the function rule for the given value. y = 6 • 4x for x = –3

Answer 1

Y = 6 * 4x. x = -3
Y = 6 ((4 * (-3))
Y = 6 * (-12)
Y = -72
This should be right if I understood the question correctly.

Answer 2

ANSWER

$y = - 72$



EXPLANATION

The given function rule is


$y = 6 \times 4x$

We want to evaluate this function for


$x = - 3$


We just have to substitute -3 into the function rule to obtain,



$y = 6 \times 4( - 3)$


This is the same as,



$y = 6 \times - 12$


This will evaluate to,


$y = - 72$
