f(5) = -2(x + 5)f(5)=

Sagot :

Given the function

[tex]f(x)=-2(x+5)[/tex]

You need to calculate f(5), this is, to calculate the value of the function when x=5

First step is to solve the multiplication, for this you have to apply the distributive property of multiplications:

[tex]\begin{gathered} f(x)=(-2)\cdot x+(-2)\cdot5 \\ f(x)=-2x-10 \end{gathered}[/tex]

Next replace x=5 in the function

[tex]\begin{gathered} f(5)=(-2\cdot5)-10 \\ f(5)=-10-10 \\ f(5)=0 \end{gathered}[/tex]
