Answer:
y=x2−4x+7
or you can do it is way y=(x−2)2+3
Step-by-step explanation:
Step-by-step explanation:
A function f(x) has an inverse, or is one-to-one, if and only if the graph y = f(x) passes the horizontal line test. A graph represents a one-to-one function if and only if it passes both the vertical and the horizontal line tests.
It is B because √2 can not be it a fraction and because √2 cannot be broken down rationally into a rational number such as √9
The answer is 60. Just multiply 20 × 3.
To find f(4), you just replace wherever x is with 4.
f(x) = 3x - 1
⇒ f(4) = 3*(4) - 1
⇒ f(4)= 12-1
⇒ f(4)= 11.
f(4) = 11 is the final answer.
Hope this helps~
