Given the piecewise functiong(x) = -343x, x= -2 (x-1)(x+ 2), x= -1 x³- x ² + 1, x ≠ -2, -1g(1) = ____

Sagot :

Answer:

g(1) = 1

Explanation:

Given the piecewise function:

[tex]g(x)=\mleft\{\begin{aligned}-343x,\text{ x=-2} \\ (x-1)(x+2),\text{ x= -1} \\ x^3-x^2+1,\text{ x}\ne-2,\text{ -1}\end{aligned}\mright.[/tex]

To find the value of g(1), this means x = 1

Looking at the piecewise function, the only function that satisfies the condition x = 1

is

[tex]x^3-x^2+1[/tex]

Because it is for all x different from -2 and -1, and x = 1 is.

Substituting x = 1 in

[tex]x^3-x^2+1[/tex]

we have:

[tex]\begin{gathered} 1^3-1^2+1 \\ \\ =1-1+1 \\ \\ =1 \end{gathered}[/tex]

Therefore, g(1) = 1
