Answer: it’s A
Step-by-step explanation: Edge 2021
Take half of the coefficient of x (which is 2/5) and square it:
[ (1/2)(2/5) ]^2 = (1/5)^2 = 1/25, or 0.04
Thus, to rewrite x^2 + (2/5)x to include a perfect square trinomial,
x^2 + (2/5)x = x^2 + (2/5)x + (1/5)^2 - (1/5)^2, or
(x+1/5)^2 - (1/5)^2, or (x + 1/5)^2 - 1/25
When x=0, y=-8, so that is the y-intercept.
When x increases by 1, y decreases by 2, so the slope is -2.
The equation of the function is
.. y = -2x -8
