Answer:

9x⁻²  is not a polynomial

Step-by-step explanation:

A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.

A polynomial is a function written in the form of ;

f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀

The degree of a polynomial is the highest power of x in the expression

9x⁻² ----in this case, the power is negative thus this is not a polynomial.

Here's a question ~<br><br>can anyone give the explanation ?​
Ahat [919]

Answer:

  • See below

Step-by-step explanation:

<u>As per the question we have:</u>

  • The y - intercept is b = -1
  • The slope has same angle with x- and y - axis.

This can be a function with the slope of m = 1 or m = - 1 as these lines must be perpendicular to each other and make 90°/2 = 45° or 45° + 90° = 135° angle with the x- or y- axis.

<u>So the lines could be:</u>

  • y = x - 1 or
  • y = -x - 1
