Question

Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.) h(t) = −t2 + t + 1 (a)
h(4)
(b) h(−1)
(c) h(x + 1)

Answer 1

Answer:

Step-by-step explanation:

h(t) = - t² + t + 1

(a). h(4) = - (4)² + 4 + 1 = - 11

(b). h( - 1 ) = - ( - 1 )² + ( - 1 ) + 1 = - 1

(c). h( x + 1 ) = - ( x + 1 )² + ( x + 1 ) + 1

- x² - 2x - 1 + x + 1 + 1 = - x² - x + 1

h( x + 1 ) = - x² - x + 1
