Answer:

the first one goes through (0,0) ||||||| the second is an exponential function so it goes through (0,1) and in a u shape going up ||||||| The third goes through (0,-1) ||||||||| The fourth goes through (0,1)

Step-by-step explanation:

these are identifiein traits so you can find wich one the graph corresponds to since u never gave us a graph.

Answer:

The graph is missing, but we can draw and describe each option.

<h3>Choice 1</h3>

y=3x

This is a linear function which passes throuhg the origin of the coordinate system because it doesn't have the constant b which is the y-intercept of the line.

The first image attached shows this function.

<h3>Choice 2</h3>

y=3x^{2} +1

This is a quadratic function. Its graph belongs to a parabola, all quadratic functions are represented by a parabola. In this case, the parabola has a vertex at (0,1). The second image attached shows this function.

<h3>Choice 3</h3>

y=3x-1

This is also a linear function, which is parallel to the first function, because they have the same slope of 3. But this one has y-intercept at (0,-1). The third image attached shows this function.

<h3>Choice 4</h3>

y=3x+1

This is also a linear function parallel to function 1 and function 3. The fourth image attached shows its graph. In this case, the line has y-intercept at (0,1).

When the function below is graphed, how many x-intercepts does it have?y = 4x2 - 12x + 9?
Sladkaya [172]
Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0)
then 0 =4x^2 -12x + 9
0=(2x-3)(2x-3)
0=2x-3
so x=3/2 that is x-intercept

Y= 5x + 13 <br> and<br> y= x + 45
arsen [322]

Answer:

x=8 and y=53

Step-by-step explanation:

Given function:

  • y=5x+13
  • y=x+45

Find x:

  • the two equation, the x and are breaked apart..
  • so find a number that they can both equal to together and has the same y.
  • multiply by 8..
  • 5·8=40
  • combine the terms for x and 13
  • 40+13=53
  • since x is 8 then if we add 8 with 45 it should be 53...
  • 8+45=53

y is:

  • this means that y=53.

Therefore, x=8 and y=53..
