Evaluate the function below for x = 3.
f(x)= 2x² – 4x+7

13 is the answer.

Step-by-step explanation:

F(3)=2(3)^2-4(3)+7

F(3)=2(9)-12+7

F(3)=18-12+7

F(3)=6+7

F(3)=13

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
