a 16

b 10

c 22

d-6

given f(x) = -8x+5 and g(x) = 10x + 2 , what is f(x) - g (x) ?

a 2x - 3

b 2x + 7

c 18x - 3

d 18x + 7

Solving for the Zeros of Quadratic Functions

The function, f(x) = –2x2 + x + 5, is in standard form. The quadratic equation is 0 = –2x2 + x + 5, where a = –2, b = 1, and c = 5. The discriminate b2 – 4ac is 41. Now, complete step 5 to solve for the zeros of the quadratic function.

5. Solve using the quadratic formula.

x =  

What are the zeros of the function

f(x) = x + 5 – 2x2?

x =  

x =  

x =  

x =
