Step-by-step explanation:
-2a + x
Putting values of a = - 2 and x = 7
-2(-2) + 7
4 + 7
= 11
The answer would be 0.468
Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.
