Which function below is the inverse of f(x)=7x-1/2

1 answer:

5 0

We write f(x) in terms of y I.e y=7x-1/2.

Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.

Make x the subject, x=2y+1/14,

Thus the inverse f(x)=2x+1/14

Sergeeva-Olga [200]

Answer:

41.1 feet to the nearest tenth.

Step-by-step explanation:

v = √2.5 r

At 65 mph the radius of the turn r

= 65 / √2.5

= 41.1 feet.

Which are the roots of the quadratic function f(b) = b2 – 75? Check all that apply.

Genrish500 [490]

$f(b)=b^2-75
\\f(b)=0
\\b^2-75=0
\\b^2=75
\\b=\pm\sqrt{75}=\pm\sqrt{25\times3}=\pm5\sqrt{3}$
