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.
Answer:
<u>CIRCLE : CIRCLE</u>
Ratio of area is the scale factor squared. So find the radii of the two circles, square both values, and simplify the ratio.
<u>SQUARE : SQUARE</u>
Ratio of area is the scale factor squared, So find the side lengths of the two squares, square both values, and simplify the ratio.
<u>SQUARE : CIRCLE</u>
Using the formulas A = s*s and A = pi*r^2, find the areas of the circle and the square. Then simplify the ratio.
D because some of the inputs have the same output therefor it is not a function
