Answer:
f(x) = –x^2 – 12x – 36
Step-by-step explanation:
The parent function, x^2, touches the x-axis at x=0. Translating it 6 units left replaces x with x-(-6) = x+6, so the function is ...
f(x) = (x+6)^2 = x^2 +12x +36
Reflecting the graph across the x-axis doesn't change the x-intercept, so Heather could be writing ...
f(x) = -x^2 -12x -36
Answer:
Mean, Median
Step-by-step explanation:
Outliers affect the mean because it is not resistant to outliers. They will affect the sum and therefore the mean.
Answer:
Step-by-step explanation:
To simplify the equation, we can just subtract the 2 fractions. First, we need to make sure they have a common denominator.
Now that the fractions have the same denominator, we can distribute the numerator and subtract.
Answer:
The Ans is B
i.e y=(1/4)x-3/4
Step-by-step explanation:
Given points (3,0) and (-5,-2)
Slope m=(y2-y1)/(x2-x1)
So m=(-2-0)/(-5-3)
=-2/-8
i.e 1/4 or 0.25
Equation of line when two points are given
y-y1=m(x-x1)
Therefore
y-0=0.25(x-3)
y=x/4-3/4
i.e y=(1/4)x-3/4
