2xy^2 and 5x^2y are not
2xy^2 and 5xy are not.
Answer:
because they all have 3 corners
Functions are written in terms of variables. The value of the function given if x = -4 is 50
<h3>Functions and values</h3>
Functions are written in terms of variables. Given the function shown;
f(x) = 3x^2 - x
If the value of x is -4, hence;
f(-4) = 3(-4)^2 - (-2)
f(-4) = 3(16) + 2
f(-4) =48 + 2
f(-4) = 50
Hence the value of the function given if x = -4 is 50
