Answer:
The value of f(-4) = -80
Step-by-step explanation:
It is given that, f(x) = -5x²
<u>To find the value f(-4)</u>
Let f(x) = -5x²
To find the value of f(-4), substitute -4 instead of x
f(-4) = -5 * (-4)²
= -5 * 16 [ since (-4)² = -4 * -4 = 16 ]
= -80
Therefore the value of f(-4) = -80

We can next plot the two points on the coordinate plane:
graph{((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(y+x-6)((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}
Step-by-step explanation:
B)decreases by one; arrow length decreases by 1/3
