Answer:
Option (A)
Step-by-step explanation:
Solution of two functions represented by the graph are the common points or point of intersection of the graphs.
From the graph attached,
Parabola and ellipse are intersecting each other at four points.
Therefore, solutions of the given non linear functions will be FOUR.
Option (A) will be the correct option.
y=-x-5. you just need to add 1 to another side to get rid of 1 from the left side
Answer:
y = 5f(x)
Please see the picture below
Step-by-step explanation:
Given the function f(x) = |x|, to transform the function y=f(x) with a vertical scaling with scale factor of 5, you should multiply the function by 5 to obtain the result;
y = 5f(x)
Please see the picture below to see a graphic solution.
