Question

If (3,y) lies on the graph of y=-(2^x) then y=

1/8

-6

-8

Answer 1

x is - 8

Explanation:
(3,y) represents (x, y)

Therefore the value for x is 3.
When x is 3;
$y = - {2}^{x}$
$y = - {2}^{3}$
Therefore y = - 8

Answer 2

If (3,y) lies on the graph of y=-(2ˣ ) then y= - 8 .

What is a function ?

A function is a mathematical expression which one variable is dependent on the other independent variable.

Ir comes with a defined domain and range.

A function is generally denoted by f(x) where x is the input.

It is given in the question

(3,y) lies on the graph of y= - ( 2ˣ )

then y  = ?

Here x = 3

y = - 2³

y = -8

If (3,y) lies on the graph of y=-(2ˣ) then y= - 8 .
