Step-by-step explanation:
Answer:
y = 3(x - 4)^3 - 3
Step-by-step explanation:
A vertical stretch factor 3 is given by 3x^3. Horizontal shift 4 to the right is given by 3(x - 4)^3. Finally we add -3 to this function to move it 3 units down.
Answer is y = 3(x- 4)^3 - 3
Answer:
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form
Substitute the value of p=2 in this, we get the equation of the parabolic mirror
Hence, the equation of the parabola that models the cross section of the mirror is
Use the point-slope formula
y-y1=m(x-x1)
y-1=-3(x-1)
y-1=-3x+3
y=-3x+4
