Answer:

Well. this is kinda trivial.

For a function f(x) = y.

The y-intercept is defined as the point where the graph of f(x) intersects the x-axis.

This always happens at x = 0.

So the y-intercept is equal to f(0).

Now, if we have the graph of f(x), you simply can see at what value of y does the graph intersect the x-axis, and that will be the y-intercept.

Sloan [31]

Answer:

D) Quadratic

Step-by-step explanation:

A function is graphed on a coordinate grid.

As the domain values approach infinity, the range values approach infinity.

Domain: If $x\rightarrow \infty$ then

Range: $y\rightarrow \infty$

As the domain values negative infinity, the range values approach infinity.

Domain: If $x\rightarrow -\infty$ then

Range: $y\rightarrow \infty$

We need to choose correct option which follows given domain and range.

Only quadratic function will follow the rule because it has even degree polynomial.

Quadratic function: $f(x)=ax^2+bx+c$

Degree = 2 and leading coefficient is positive.

Domain: $x\belong (-\infty,\infty)$

Range: $y\belong (b,\infty)$

Hence, D is correct option.

6y+12=-2x x+3y=-6 In y form

Vlada [557]

Answer:

both equations reduce to y = -1/3x -2

Step-by-step explanation:

In each case, subtract the term not containing y and divide by the coefficient of y.

1. 6y = -2x -12 . . . . 12 was subtracted from both sides

y = -1/3x -2 . . . . . . the equation was divided by 6

2. 3y = -x -6 . . . . . . x was subtracted from both sides

y = -1/3x -2 . . . . . the equation was divided by 3

1 2. Verify that (1 - cos^20) CSc^20 = (4 Points)

dolphi86 [110]

(1-cos^2(x)) csc^2(x)=1

one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)

we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:

sin^2(x) x 1/sin^2(x) = 1

sin^2(x)/sin^2(x) =1

the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same

so then 1=1 Therefore LHS=RHS

Hope this helps
