Answer:
Step-by-step explanation:
Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.
To find it, we use the given point of g, (2,1)
So g(2) = 1
meaning that
a·2² = 1
4a = 1
a = 1/4
Answer:
0.0000000692
Step-by-step explanation:
The number 
is written in scientific notation. To convert to standard notation adjust the decimal point to adjust the number according to the exponent. Since the exponent is -8 then the decimal point moves to the left 8 place values.
A: Yes because for each x value, there is only one corresponding y value.
B: For the first relation, y is half of x, so f(x)=x/2. If x is 8, y is 4.
Plug in the value of x for the second function. 3(8)-10=24-10=14.
The second relation has a greater value.
C: 80=3x-10,
90=3x
x=30
