F(x)=5x^4 helllllpppppp
Marina CMI [18]

we can use properties of functions to find this out


for f(x)=ax^b


if b is even, then the ends of the function go in the same directions (both up or both down)

if b is odd, then the ends of the function go in different directions (one up and one down)


if a is positive and b is even, then both ends point up

if a is positve and b is odd, then it goes from bottom left to top right

if a is negative and b is even, then both ends point down

if a is negative and b is odd, then it goes from top left to bottom right


given f(x)=5x^4

a=5>0

b=4 which is even

so it has both ends pointing up

bottom right graph is yo answer
