Which of the following statements are true about the quadratic function f (sc) = a(
z
apply.
h)" + kthat has no real zeros? Select all that
If the value of a is positive, then the graph opens upward.
If the value of k is negative, then the value of a is negative.
The value of h cannot be zero.
The value of k cannot be 0.
The value of a must greater than one, so the graph is vertically stretched.
Asse
The values of a and k must have opposite signs.
Gray
If the value of a is positive, then the value of k is negative.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
