**GIVING BRAINLIEST ASAP** Are the following polynomials a function
f(x)=5x^(4)+3x^(2)+6x^(-1)-3
f(x)=(7)/(8)x^(3)+2x^(5)-6x+17
f(x)=5\sqrt(3+4x)
f(x)=(1)/(x^(2))+(1)/(x)-12x^(2)

f(x)=5x^(4)+3x^(2)+6x^(-1)-3:yes

f(x)=(7)/(8)x^(3)+2x^(5)-6x+17:yes

f(x)=5\sqrt(3+4x):No

f(x)=(1)/(x^(2))+(1)/(x)-12x^(2):Yes

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.
