Evaluate the function rule for the given value. y=6*4^x for x=-3

Y = 6 x 4^x.         x = -3 

you change x in the equation for -3 

y= 6 x 4^ -3 

if you do it in the calculator, remember to put parenthesis in between -3 

y = 6 x 1/64

y =  3/32 or 0.09375

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
