Least value is negative infinity
Hello :
<span>slope of the red line is : a
a×(-5) = -1
a=1/5</span>
3(x + 5)² + 6
the equation of a parabola in vertex form is
y = a(x - h)² + k
here a = 3 , h = - 5 and k = 6 thus
f(x) = 3(x + 5)² + 6
Step-by-step explanation:
What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.
So for X = 0
y = 2(0)+5 = 5
x = 1
y = 2(1)+5 = 7
x = 3
y = 2(3)+5 = 11
x = 5
y = 2(5)+5 = 15
x = 10
y = 2(10)+5 = 25
Now for what you do is place the correspanding value into the graph.
(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)
Your answer is to the question 16,4
<span>Form of the equation: y = mx + b
---
You are given that y = 8 when x = 7.
And you are given that m = -1.2
-----
Substitute for those letters and solve for "b"::
8 = -1.2*7 + b
8 = -8.4 + b
b = 8 + 8.4 = 16.4</span>
