Answer: y = -
x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = - x - 6
Answer:
y= 288
Step-by-step explanation:
Please see the attached picture for full solution.
Answer:
- The range of the given function is [6, + ∞)
Step-by-step explanation:
It is assumed the function is:
We know the square root is non-negative, so:
- x - 8 ≥ 0 therefore the function gets values
We can show this as:
You have the intercepts and x-coordinate of the vertex correct. There appears to be a math error in the calculation of the y-value of the vertex.
f(7/8) = (4*7/8 -7)*(7/8) -15 = -49/16 -15 = -289/16 = -18.0625
