Can someone help me with 14 and a few others I need help ):

26, -0.85, 17

Step-by-step explanation:

hi! so for 14, you can plug in -11 for every x in the equation.

f(-11)= 15-(-11)

=15+11

=26

your answer is 26.

for 15, we can plug in 0.3 for x.

g(0.3)=-2.5(0.3)-0.1

= -0.75-0.1

= -0.85

your answer is -0.85.

for 16, you can plug in -17 for x.

f(-17)= -(-17)

=17

your answer is 17.

14:   26

15: -8.5

16:  17

Step-by-step explanation:

The f(x) basically gives you what x is, as the inside of parenthesis means the value of x. You then can plug in x into the equation for each of the equations. Whenever you get something like 24- (-42) The negatives cancel out and you add the two values together instead.

Hope this helps!
