What are the zeros of f(x) = x2 - x-30?
re the zeros

x = 6 and x = -5

Step-by-step explanation:

The zeros are what 2 x-values makes this function equal to zero.

So we need to find  

Now we need 2 numbers multiplied that gives us -30 (constant) and added gives us -1 (coefficient in front of x).

The two numbers are : -6, and 5

Now we can write:

Hence the zeroes are x = 6 and x = -5

B

Step-by-step explanation:

g(2)=-7 because -(2)-5=-7

f(-7)=-18 because 2(-7)-4=-18
