Question

dada a função f )x) = - 2x + 3 determine f (2)​

Answer 1

$\begin{bmatrix}f=-2x+3\\ f=\left(2\right)\end{bmatrix}\\\\\begin{bmatrix}-2x+3=2\end{bmatrix}\\\\f=-2\cdot \frac{1}{2}+3\\\\-2\cdot \frac{1}{2}+3\\\\=-1+3\\\\-1+3=2\\\\f=2\\\\x=\frac{1}{2},\:f=2$

Answer 2

Resposta: f(2)= -2.2+3

-4+3=-1
