Question

One quick question!

Answer 1

ya :-)

Answer 2

f(0) means find f(x) when x = 0

Answer 3

so which piece corresponds to x = 0?

Answer 4

if the piecewise function notation confuses you, it just means

f(x) = x^2 + 1 if x <= 0

OR

f(x) = 2x - 4 if x > 0

Answer 5

so x^2+1?

Answer 6

good

Answer 7

if x = 0, then it corresponds to the x<=0 piece

so you plug in x = 0 into f(x) = x^2 + 1

Answer 8

f(0)=1?

Answer 9

good

Answer 10

do the same for f(-2)

Answer 11

because -2 is less than 0, this means that x = -2 satisfies x < = 0

so you're still working with f(x) = x^2 + 1

Answer 12

f(-2)=5?

Answer 13

good

Answer 14

Thank you!
