The zeros are -8, -1, 2, so you can write the function as f(x)=(x-(-8))(x-(-1))(x-2)=(x+8)(x+1)(x-2).
Expand:
The function is f(x)=x³+7x²-10x-16.
The missing value is 7.
Answer:
h(0) = -4
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
h(x) = -3x -4
h(0) = -3·0 -4 = 0 -4
h(0) = -4
_____
<em>Additional comment</em>
In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.

Answer:
y = 7/2x+5
Step-by-step explanation:
To find the slope we need two points
(-2,-2) and (0,5)
We can find the slope from the formula
m = (y2-y1)/(x2-x1)
m = (5--2)/(0--2)
m = (5+2)/(0+2)
m = 7/2
The slope is 7/2
The y intercept, or where it crosses the y axis, is 5
Using the slope intercept formula for a line
y= mx+b
y = 7/2x+5
