What is y=x^2+74, translated 2 units up and 5 units left
2 answers:
Answer:
y = x² + 10x + 101
Step-by-step explanation:
Start with the basic function: y = x² + 74.
To shift the parabola up two units, you add two units to the value of y. The equation becomes
y = x² + 76
To shift the parabola five units to the left, you must add five units to the value of x. The equation for the parabola becomes
y = (x + 5)² + 76
y = x² + 10x + 25 + 76
y = x² + 10x + 101
The figure below shows the graphs of
y = x² (red)
y = x² + 76 (blue) (shifted up two units)
y = x² + 10x + 101 (green) (shifted left five units)
