Answer:
y=(x+2)²-3
Step-by-step explanation:
when y=x² shifted 3 units down
its eq. is y=x²-3
when it is also shifted 2 units left then its eq. is
y=(x+2)²-3
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic are a = 1, b = 6 and c = 4.
-b
The axis of symmetry is x = -------- , which here is x = -6/2, or x = - 3.
2a
Use the given quadratic to find the vertical coordinate of the vertex:
y = (-3)^2 + 6(-3) + 4 = 9 - 18 + 4 = y = -5.
The axis of symmetry is x = -3, and the vertex is (-3, -5).
5.30 x 285 =1225.5
this is the answer hope it helps

Answer:
y = -2x + 3
Step-by-step explanation:
The given equation is:
First we need to find the slope of the tangent line. This can be done by finding the derivative of the given function.
Slope of the tangent will be the value of the derivative at the given point. So the slope of tangent is:
Now we have slope of the tangent line and a point (0, 3) on the tangent. The point (0,3) is the y-intercept of the tangent line. So we can use slope-intercept form to directly write the equation of the line.
The slope intercept form of an equation is:
y = mx + c
where m is the slope and c is the y-intercept.
Using the values: m = -2 and c = 3, we get:
y = -2x + 3
This equation represents the tangent line
