Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1
vlabodo [156]

Answer:

A) x = y^{2}

Step-by-step explanation:

An equation is a function of x when x is the independent variable, that is:

y = f(x) (1)

Where y is the dependent variable.

According to this, x = y^{2} does not represent a function of x, since the independent variable is a function of y, that is, x = f(y). Therefore, the correct answer is A.

Given f(x)=3x^2+2x-10 and g(x)=3x-3 If g(f(x))=2
STatiana [176]

Answer:

f(x)=3x^2+2x-10 if x=2

f(x)=3(2)^2+2(2)-10

f(x)=3(4)+2(2)-10

f(x)=12+4-10

f(x)=16-10

f(x)=6

g(x)=3x-3 if g(x)=2

g(x)=3(2)-3

g(x)=6-3 =3

Step-by-step explanation:

<u>f</u><u>(</u><u>x</u><u>)</u>
