Question

A parent function f(x)=4x-5 is transformed to f(x)+3. which statement about the graph of f(x)+3 is true?

a) the graph shifts 3 units up from the parent graph, the x-intercept increases by 3.
b) the graph shifts 3 units up from the parent graph, the y-intercept increases by 3.
c) the graph shifts 3 units down from the parent graph, the x-intercept increases by 3.
d) the graph shifts 3 units down from the parent graph, the y-intercept increases by 3.

Answer 1

B

Explanation:

f(x) is just another way of saying y, so this function is really y=4x-5. So if you do y+3 then the y intercept will increase by 3 shifting the graph up 3 units.
