I think these answers are correct but I am not 100% sure
Answer:
x=1/2
x=-o.5, x=-2
Step-by-step explanation:
To find x intercept/zero, substitue f(x)= 0-0 which gives you 0=2x+1. Then you solve for x to get x=-1/2 which is the answer. x=-o.5, x=-2 is the alterative form. Pls mark as brainlist if right.
F(6) = -(6)^2 + 6(6) - 4
= -36 + 36 - 4
= -4
A
Remark
You must use the sin law to find this.
Multiply through by 12
12 * *12
0.5269 = sin(x)
Now you have to use the inverse of the sine function.
Use your calculator for that

There sometimes is a second answer. I don't think there is in this case.
