TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
Mean = (20 + 14 + 29 + 39 + 33 + 25 + 19 + 35)/8 = 214/8 = 26.75
Range = highest number - smallest number = 39 - 14 = 25
Answer:
C
Step-by-step explanation:
F(X)=(X+2)\7 BY cross multiply
7y=x+2 therfor f(x)=y,
now interchanging y and x,
7x-2=y.
Answer:
x > -7
Step-by-step explanation:
20 + 8 > -4x
Simplify
28 > -4x
Divide both sides by 4
-28/4 < x
-7 < x
x > -7
