Answer:
See below. <u><em>I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3</em></u>
Step-by-step explanation:
Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3
For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3. f(0) = 3
f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.
= 8*4 + 14 +3
= 32 + 17 therefore f(-2) = 49
<u>x</u> <u>f(x)</u>
-2 49
-1 18
0 3
1 4
2 21
- 2*(1+3)=8 => 2*4=8, 3*(4+5)=27=> 3*9=27. 4*(9+7)=64=> 4*16=64. 5*(16+9)=125 => 5*25= 125.
Answer:
Slope = 4
Step-by-step explanation:
Y = x
when x < -1
not equal to (≤) so no solid circle.
plot points
x | y
-1, -1
-2, -2
-3, -3
Next one is...
y = -x
when x ≥ -1
solid circle for equal to
look at points
x | y
-1, 1
0, 0
1, -1
2, -2
As you can see it's the last graph in bottom right corner.
