Mr. Patel decided to challenge his Algebra I students by asking them to describe the effect 2f would have on the function f(x) = x2. Use your understanding of horizontal and vertical stretches to explain the result.

5

step-by-step explanation:

the answer is 40.

proof:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
