The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 =
{-5, 3}
Answer:
169/4
Step-by-step explanation:
x² - 13x + c
x² -2(x)(13/2) +(13/2)²
(13/2)² = 169/4 or 42 ¼
7 |1 -8 10
X. 7. -7
1 -1 3
A remainder is 3
The output k at input t = -7 is -89
Step-by-step explanation:
In order to find the value of a expression on given number, we put the number in given expression in place of independent variable
So,
Given expression is:

It is given that the value of t has to be -7
so putting t=-7 in the expression

Hence,
The output k at input t = -7 is -89
