Given: [tex]g(x) = (x-6)(x-3)(x+2)[/tex]

3.1 Calculate the [tex]y[/tex]-intercept of [tex]g[/tex].


Sagot :

To find the [tex]\( y \)[/tex]-intercept of the function [tex]\( g(x) = (x-6)(x-3)(x+2) \)[/tex], we need to determine the value of [tex]\( g(x) \)[/tex] when [tex]\( x = 0 \)[/tex]. The [tex]\( y \)[/tex]-intercept is the value of the function at this point.

Here are the steps:

1. Substitute [tex]\( x = 0 \)[/tex] into the function [tex]\( g(x) = (x-6)(x-3)(x+2) \)[/tex].

[tex]\[ g(0) = (0-6)(0-3)(0+2) \][/tex]

2. Simplify the expression inside the parentheses:

[tex]\[ g(0) = (-6)(-3)(2) \][/tex]

3. Multiply the values together:

[tex]\[ (-6) \times (-3) = 18 \][/tex]

[tex]\[ 18 \times 2 = 36 \][/tex]

Therefore, the [tex]\( y \)[/tex]-intercept of the function [tex]\( g(x) = (x-6)(x-3)(x+2) \)[/tex] is [tex]\( 36 \)[/tex].

In other words, the point where the graph of the function intersects the [tex]\( y \)[/tex]-axis is [tex]\((0, 36)\)[/tex].
