Evaluate 4-2f4−2f4, minus, 2, f when f=1f=1f, equals, 1.

The value of 4-2f is 2.

Step-by-step explanation:

Since we have given that

Let

Here, f = 1

And we need to evaluate the above value.

To evaluate the value of expression, we have to substitute f with its value i.e. f = 1.

So, we put f = 1 in the given expression.

We get that

Hence, the value of 4-2f is 2.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
