Is x^2/7+1 a polynomial

is a polynomial .

Step-by-step explanation:

We have , the following expression x^2/7+1 ,i.e. .

A polynomial function is a function such as a quadratic, a cubic, a quadratic, and so on, involving  only non-negative integer powers of x. Some examples are :

f(x)=3x−2Linear polynomial (linear function)

f(x)= Quadratic polynomial

f(x)=−    Cubic polynomial with no quadratic term

f(x)=(x−3)2(2x−1)

A polynomial of degree n is a function of the form:

for a quadratic polynomial , here equation :

⇒

⇒which is equivalent to .Hence, is a polynomial .

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
