Evaluate the function at the specified value of the independent variable and simplify. $$f ( y ) = 2 y + 7$$
$f ( - 1.4 )$
A) $- 2.8 \mathrm { y } + 14$
B) $- 9.8$
C) $4.2$
D) $- 1.4 y + 7$
E) $- 1.4 y - 7$

Question

Quizplus · Accepted Answer

To evaluate the function, we substitute -1.4 in place of y in the expression for f(y):
$$f(-1.4)=2(-1.4)+7=-2.8+7=4.2$$
Therefore, the correct choice is C.

Evaluate the Function at the Specified Value of the Independent f(y)=2y+7f ( y ) = 2 y + 7f(y)=2y+7

Evaluate the Function at the Specified Value of the Independent $f ( y ) = 2 y + 7$
