Question: $$F ( x ) = 1 x + 2 1$$

Solution

The photo shows a linear function: \[ F(x) = 1x + 21 \] This is in the slope-intercept form \( y = mx + b \), where the slope \( m = 1 \) and the y-intercept \( b = 21 \). If you need assistance with calculations or specific questions related to this function, please let me know!
