Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
Answer: This is a quadratic equation in x and can be solved using the quadratic formula: x = (-b +_ (b^2 - 4 ac)^1/2) / (2 * a)
or (-7 +- (49 - (4 * 2 * 6))^1/2) / (2 * 2) where a=2, b=7, and c=6
and x = (-7 +- (49 - 48)^1/2) / 4 = (-7 +- 1) / 4
giving x = -8/4 and -6/4 or -2 and =3/2
Answer:
9. 89
Step-by-step explanation:
A squared + B squared = C squared
7 squared + 7 squared = 98 squared
Find the square root of 98 (I recommend using a calculator)
You should get 9.89 as an answer.
