The graph y=f(x) (where f(x) is a quadratic function) intersects the x-axis at A (-1,0) and B and has a maximum point at (0.5, 6). The equation f(x)= k has exactly one solution.
Write down the value of k.
Would k just be 6, as this is the y value at the turning point of the graph?

The box plots show the distributions of the numbers of words per line in an essay printed in two different fonts.which measure of center would be best to compare the data sets? the median is the best measure because both distributions are left-skewed.the mean is the best measure because both distributions are left-skewed.the median is the best measure because both distributions are symmetric.the mean is the best measure because both distributions are symmetric
