In the equation \( y = -3 \cos (4 x - 2) + 10 \), the vertical shift is determined by the constant term outside the cosine function. Here, it is \( +10 \), meaning the entire graph shifts upward by 10 units from the standard position of the cosine function. For horizontal shifts, we look inside the cosine's argument. The expression \( 4x - 2 \) indicates a shift caused by the term \( -2 \). To find the horizontal shift, we set \( 4x - 2 = 0 \), leading to \( x = 0.5 \). Since the cosine function is periodic, we consider both shifts together; thus, this function is shifted 0.50 units to the right and 10 units up from its standard position!
