3x2+8x-10 // the answer is 8x
Answer: The first one is "translated 4 units down". The second one is "vertically stretched by a factor of 4".
Recall that y = f(x). When we say f(x)-4, we really mean y-4 so that means each y coordinate of all the points on the graph have been reduced by 4. Visually this shifts the graph down 4 units. A translation in geometry is the technical term for shifting.
When we say 4*f(x), we are multiplying each y coordinate by 4. A point like (1,2) turns into (1,8) for instance. If you apply this to every point on the graph, then the curve is stretched vertically to be 4 times taller than it usually is; which is an informal way of saying "vertically stretched by a factor of 4"
Answer:
10(x−8)
Step-by-step explanation:
10x-80
-> Both have a factor of 10
10x / 10 = x
80 / 10 = 8
10(x - 8)
I hope this helps you
slope=1-2/2-(-3)
slope = -1/5
y-(-3)= -1/5 (x-2)
y+3= -1/5 (x-2)
