Answer:

  • f(x) = 4x - 3

Step-by-step explanation:

Given the table of domain and range

<u>Using the points, lets find the slope-intercept form</u>

  • y = mx + b

<u>The slope</u>

  • m = (5-1)/(2-1) = 4/1 = 4

<u>y-intercept</u>

  • 5 = 4*2 + b
  • b = 5 -8
  • b = -3

<u>So the function is</u>

  • y = 4x - 3
  • or
  • f(x) = 4x - 3

Answer:

\sf f(-3) = 23

<u>given:</u>

\sf f(x) = 3x^2 -4

to find the output, replace x with the given integer.

solve:

\sf f(-3) = 3(-3)^2 -4

\sf f(-3) = 3(9) -4

\sf f(-3) = 27 -4

\sf f(-3) = 23

Help me with all of them
inessss [21]
Use the equation
For A. The problem would be set up like so

5 _ -1
--------
4 _ -2

Start by subtracting 5 minus -1 which is 6 because minus a negative becomes a positive then subtract 4 minus -2 which is 6, remember minus a negative becomes a positive, then divide 6/6 to get 1

For B.

-5 _ -0
----------
3 _ -1

Again subtract -5 by -0 which no matter what will be -5. Then make -1 positive because it's a subtracted negative so it becomes 3+1 which gives you 4. Your answer is -5/4

If you need help with the rest message me good luck

Write the equation of the ellipse graphed below.
Lana71 [14]

Answer:

Step-by-step explanation:

This is a horizontally stretched ellipse.  That means that the horizontal line which is represented by the x-axis is the longer one.  The equation for this type of ellipse is

\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1

In an ellipse, the a value is ALWAYS bigger than the b value, and since the x-axis represents the longer axis, the a goes under the x-squared term.  

To solve for the h, the k, the a, and the b, we simply have to do some counting.  The center of the ellipse, the (h, k) our of equation, is sitting at (4, 6).  Put them where they belong in the equation.  The a axis (the horizontal one) is 8 units long, and the b axis (the vertical one) is 4 units long.  Square both of them and put them where they belong in the equation:

\frac{(x-4)^2}{64}+\frac{(y-6)^2}{16}  =1

There you go!
