Question

Identify whether each polynomial is quadratic, linear, or neither

Answer 1

Explanation:

1. quadratic

2. linear

3. neither

4. linear

5. quadratic

6. linear

Answer 2

i) f(x) = x^2 + 3x + 4, here the degree of the function is 2. So it is quadratic.

ii) g(x) = 9 + 7x, here the degree of the function is 1. So it is linear.

iii) h(x) = x^-2 -36, here the degree is -2, so it is neither.

iv) p(x) = 4x, here the degree of x is 1, so it is linear.

v) R(x) = x^2 +3, here the degree of x is 2, so it is quadratic.

Vi) c(x) = 1500 + 4x, here the degree of x is 1, so it is linear.

Explanation:

If the highest degree of the function is 2, then it is quadratic.

If the highest degree of the function is 1, then it is linear.

i) f(x) = x^2 + 3x + 4, here the degree of the function is 2. So it is quadratic.

ii) g(x) = 9 + 7x, here the degree of the function is 1. So it is linear.

iii) h(x) = x^-2 -36, here the degree is -2, so it is neither.

iv) p(x) = 4x, here the degree of x is 1, so it is linear.

v) R(x) = x^2 +3, here the degree of x is 2, so it is quadratic.

Vi) c(x) = 1500 + 4x, here the degree of x is 1, so it is linear.

Hope this will helpful.
