Answer:
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.
Step-by-step 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.
Thank you.
