x intercept = where the function crosses the x axis (x,0)

y intercept = where the function crosses the y-axis (0,y)

A. y=7/2x-2

x intercept , replace y by 0 and solve for x:

0 =7/2x-2

2= 7/2 x

2 / (7/2) = x

x= 4/7

y-intercept, replace x by 0 and solve for y

y= 7/2x-2

y= 7/2 (0) -2

y=-2

B.

x-intercept:

x=-3

y-intercept

0=-3

It doesn't have a y-intercept.

Which graph represents the function f(x)=(x-5)^2+3
hammer [34]

Answer:

Parabola

Step-by-step explanation:

We are given that a function

f(x)=(x-5)^2+3

The given function is an equation of parabola along y- axis.

General equation of parabola along y- axis  with vertex (h,k) is given by

(y-k)=(x-h)^2

y=(x-h)^2+k

Compare it with given equation then we get

h=5, k=3

Vertex of given parabola =(5,3)

Substitute x=0 then we get

f(0)=(0-5)^2+3=28

y-intercept of parabola is at (0,28).

Match the following items.
Misha Larkins [42]

Based on the points on the graph, the correct matches are:

  • A - (-4, -2).
  • B - .(2, -4)
  • C - (4, -2).
  • D - (2, 5)
  • E - (-1, 1)
  • F - (-5, 0)
  • G - (4, 2)
  • H - (0, -5)

<h3>How are points located on a graph?</h3>

To find a point, you need to look at the x-axis first and then the y-axis.

Find where the point is located on the x-axis, and then look for where the point intersects with the y-axis point.

For instance, the point A is located at (-4, -2) so look at the -4 point on the x axis, then go down to the -2 point on the y-axis. You'll find point A.
