EVALUATE EACH FUNCTION FOR THE VALUE SPECIFIED

Question

f(x)= x^2 -7x +10: find (a) f(0), (b)f(5), and (c)f(-2)

Answer 1

The function f (x) = x^2 - 7x + 10.

a).

To find f (0), substitute the value x = 0 in f(x) = x^2 - 7x + 10.

f (0) = 0^2 - 7(0) + 10

= 0 - 0 + 10

= 10.

f (0) = 10.

b).

To find f (5), substitute the value x = 5 in f(x) = x^2 - 7x + 10.

f (5) = 5^2 - 7(5) + 10

= 25 - 35 +10

= 35 - 35

= 0.

f (5) = 0.

c).

To find f (- 2), substitute the value x = - 2 in f(x) = x^2 - 7x + 10.

f (- 2) = (- 2)^2 - 7(- 2) + 10

= 4 + 14 + 10

= 28.

f (- 2) = 28.
