For f(x)=x^2,sketch the graph of g(x)=f(-5x+10)
1 answer:
The graph of g(x) = f(-5x+10) is given in the figure.
<h3>What is a graph?</h3>A diagram showing the relation between two variable quantities,each measured along one of a pair of axes at right angles.
It is given that f(x) = x^2
and g(x ) = f(-5x+10)
Now putting the value of f(x) in g(x) we get,
g(x) = f(-5x+10) = (-5x+10)^2
So, g(x) = (-5x+10)^2
now, making the table for g(x),
<u><em>x </em></u><u>g(x)</u>
0 100
1 81
2 0
3 25
4 100
5 225
Hence,the graph of g(x) = f(-5x+10) is given in the figure.

Answer:
Speed of first skier = 5 km/h
Speed of second skier = 10 km/h
Step-by-step explanation:
Given:
Distance between skiers = 30 km
Time after which they meet = 2 hours
Second skier is 5 km/h faster than the first skier.
To find speed of each skier.
Solution:
Let the speed of first skier be in km/h =
<em>Distance covered in km 2 hours will be = </em>
Speed of second skier in km/h can be given as =
<em>Distance traveled by second skier after 2 hours will be = [Using distribution]</em>
Since, the skiers were 30 km apart initially, so the total distance covered by both of them when they meet after 2 hours will be = 30 km
Thus, we have:
Solving for
Subtracting both sides by 10.
Dividing both sides by 4.
Speed of first skier = 5 km/h
Speed of second skier = = 10 km/h
