Given the table below, evaluate the following:
NeX [460]

Part A

See the image labeled "part A". We'll use the values marked in blue and red for f(2) and g(2) respectively. These values are the function outputs when the input is x = 2.

(f-2g)(x) = f(x) - 2*g(x)

(f-2g)(2) = f(2) - 2*g(2)

(f-2g)(2) = 1 - 2*3

(f-2g)(2) = -5

Answer: -5

=====================================================

Part B

See the image labeled "part B". We'll use the values marked in blue and red for g(-1) and f(0) respectively.

We have to start with g(-1) and then chain it to finding f(0) afterward.

g(-1) = 0

f(g(-1)) = f(0) = 9

Answer: 9

=====================================================

Part C

See the image labeled "part C". We'll use the values marked in blue and red for g(-2) and g(-3) respectively.

Because g(-2) is the innermost function, it must go first, then g(-3) can go next.

g(-2) = -3

g(g(-2)) = g(-3) = 8

Answer: 8

What are the coordinates of the y-intercept of the line who's equation is 12x + 13y =8???
Ierofanga [76]

Answer:

y-intercept = (0,  \frac{8}{13} ).

Step-by-step explanation:

Given the linear equation in standard form, 12x + 13y = 8:

We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.

12x + 13y = 8

Subtract 12x from both sides:

12x + 13y - 12x = - 12x + 8

13y = - 12x + 8

Next, divide both sides of the equation by 13 to solve for y:

\frac{13y}{13} = \frac{-12x + 8}{13}

y = \frac{-12x + 8}{13} or  y = -\frac{12}{13} x + \frac{8}{13}

Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is  the point where the graph of the linear equation crosses the y-axis).

Let x = 0:

y = -\frac{12}{13} x + \frac{8}{13}

y = -\frac{12}{13} (0) + \frac{8}{13}

y = \frac{8}{13}

Therefore, the value of y when x = 0 is \frac{8}{13} . This is the y-intercept, and its coordinate is (0,  \frac{8}{13} ).
