Question

Given that (5,4) is on the graph of f(x), found the corresponding point for the function f (x)+4

Answer 1

The corresponding point is (5,8)

Explanation:

In this problem we know that

The rule of the transformation is equal to

(x,f(x)) ------> (x,f(x)+4)

so

for the point (5,4)

x=5, f(x)=4

substitute

(5,4) ------> (5,4+4)

(5,4) ------> (5,8)

therefore

The corresponding point is (5,8)
