Graph the following pair of quadratic functions and describe any similarities/differences observed in the graphs. f(x) = 5x² – 3
g(x) = 5x + 3
a. both f and g open downward; low point of fis 3 units below the x-axis; the low point of g is 3 units
above the x-axis
b. both f and g open upward; low point of fis 3 units above the x-axis; the low point of g is 3 units
below the x-axis
both f and g open upward; low point of fis 3 units below the x-axis; the low point of g is 3 units
above the x-axis
d. both f and g open downward; low point of fis 3 units above the x-axis; the low point of g is 3 units
below the x-axis
