A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.

torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2}+k$

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

$y=a(x-1)^{2}-4$

we have

An x-intercept of (-1,0)

substitute and solve for a

$0=a(-1-1)^{2}-4$

$0=4a-4$

$4a=4$

$a=1$

The equation is

$y=(x-1)^{2}-4$

<u><em>Verify the y-intercept</em></u>

For x=0

$y=(0-1)^{2}-4$

$y=-3$

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

see the attached figure

Carl is using a pine board to make a frame for a picture . He wants the dimensions of the frame to be 2 feet by 18 inches. How l

Tems11 [23]

You could find the need of pine board by finding the perimeter of the frame. But first you need to equalize the units, because one of them is in feet and the other one is in inches.
18 inches = 18/12 feet
18 inches = 1.5 feet

perimeter = l + w + l + w
perimeter = 2 + 1.5 + 2 + 1.5
perimeter = 7

The perimeter is equal to 7 feet, therefore Carl needs 7 feet of pine board
