Indeed, a fare of $40 is a fair charge for the cab ride.
Explanation
Sheri's cab fare totaled $32, with a gratuity rate of 20%.
The gratuity amount is:
Thus, the total cab fare including gratuity is:
Since Sheri issued a $40 check to the cab driver, it indicates she provided ($40 - $38.40) or an extra $1.60 to the cab driver. Consequently, the $40 payment is reasonable for the cab fare.
The adjusted equation , indicating that the graph has been altered 4 units leftward and 6 units downward.
Clarification:
The parent equation is .
The transformed equation is .
Applying the function transformation rules, it's clear that the parent function has been modified into the function
.
According to the function transformation rules,
indicates shifting the function b units to the left.
Thus, the transformed function reflects a shift 4 units to the left.
Additionally, from the function transformation rules, we understand that,
indicates shifting the function b units downward.
Consequently, the transformed function mirrors a shift of 6 units downward.
In summary, the adjusted equation , shows the graph shifted 4 units to the left and 6 units downward.
