Graph the following pair of quadratic functions and describe any similarities/differences observed in the graphs. h(x)=1/3x^2
f(x)=2x^2
a. both open upward; h is wider than f
b. both open downward; h is narrower than f
C. h opens downward; fopens upward; h is wider than
d.
h opens upward; fopens downward; h is narrower than f

Please help thank you so much ..

The answer is a. both open upward; h is wider than f

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer is 31.27mph
