For the function f defined b f(x)=x^2+2x+3 find f(-x), -f(x), and -f(-x).
Rom4ik [11]

Answer:

see explanation

Step-by-step explanation:

To evaluate f(- x) substitute x = - x into f(x)

f(- x) = (- x)² + 2(- x) + 3 = x² - 2x + 3

-----------------------------------------------------

- f(x) = - (x² + 2x + 3) ← distribute parenthesis by - 1

       = - x² - 2x - 3

-----------------------------------------------------------

- f(- x) ← substitute f(- x) from above

= - (x² - 2x + 3) ← distribute parenthesis by - 1

= - x² + 2x - 3

Does this graph show a function? Explain how you know.
liq [111]

The correct option regarding whether the graph shows a function is given by:

C. Yes; the graph passes the vertical line test.

<h3>When does a graph show a function?</h3>

In a function, one value of the input can be related to only one value of the output. Hence, in a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis), which will mean that the graph will pass the vertical line test.

In this problem, the condition is respected, hence option C is correct.

How to find slope and y intercept 6x-5y=15?
iogann1982 [59]
We need to put this equation in y = mx + b form because in this form, the slope will be in the m position and the y intercept will be in the b position. So basically, we solve for y.

6x - 5y = 15 ....subtract 6x from both sides
-5y = -6x + 15...divide both sides by -5
(-5/-5)y = (-6/-5)x + (15/-5)...simplify
y = 6/5x - 3

y = mx + b...remember, m is ur slope and b is ur y int
y = (6/5)x + (-3).....ur slope(m) = 6/5 and ur y int (b) = -3

How do you solve 2x=12+2y
Sonbull [250]
2(x) - [12 + 2y) ➡ 0
2(x - y - 6)
2 ➡0 {It doesn't have any solution for the equation}
x - y - 6 ➡0
y ➡ 6 over -1 ; x ➡6 over 1
The slope = 1

Therefore your answer would have to be ➡
y= 6 over -1 ; x = 6 over 1 ; slope = 1
