Evaluate the piecewise function below for f(1): f(x) = { x^2 - 5 if x < = -1 3 - x^2 if -1 < x < 1 2x^2 + 3 if x > = 1 } write your answer as a single number.

We need to find f(1)

f(1) means x=1

Now we look at the three inequalities and choose the one where x=1 satisfies

x<=-1 , -1<x<1  and x>=1

x=1 satisfies the inequality x>=1

so we use the third function to find f(1)

We plug in 1 for x and find f(1)

= 2 + 3 = 5

f(1) = 5
