Which equation represents a function of x that is not linear?

AnnyKZ [126]

Answer:

y = 4x+3x^2

Step-by-step explanation:

For an equation to be linear, x must have a power of 1

y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)

Answer:

$a=\sqrt{33}$

Step-by-step explanation:

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

a² = 7² -4²

a² = 49 -16 = 33

a = √33

Answer:

$(f\cdot g)(x)=2x^2+10x+12$

$(f-g)(x)=-x-1$

$(f+g)(1)=10$

Step-by-step explanation:

$\tt f(x)=x+3$

$\tt g(x)=2x+4$

$(f\cdot g)(x)=f(x)\cdot g(x)=(x+3)(2x+4)=2x^2+4x+6x+12$

$=2x^2+10x+12$

$(f-g)(x)=f(x)-g(x)=x+3-(2x+4)=x+3-2x-4$

$=-x-1$

$(f+g)(1)=f(1)+g(1)=1+3+2(1)+4$

$=4+2+4=10$
