Question

if f (x) = x square - 2x+5 and t=y-2, find f(t)​

Answer 1

Step-by-step explanation:

given,f(x)=x²-2x+5

t=y-2

therefore f(t)=(y-2)²-2(y-2)+5

=y²-2²-2(2)(y)-2y+2+6

=y²-4-4y-2y+7

=y²-6y+3

Answer 2

Answer:

4

Step-by-step explanation:

First, find f(2) by plugging in 2 for x in the expression 2x−5.

We get f(2)=2(2)−5=4−5=−1.

Similarly, f(5)=2(5)−5=5.

Then, f(2)+f(5)=−1+5=4
