F (x)=x+3x find f(2)

f(x)=3x-2 find f(-10)

help please

1) f(2) = 8

2) f(-10) = -32

Step-by-step explanation:

Whenever you see a problem that asks something like what f(2) or f(-10) is, it is asking you to substitute whatever number is in the parentheses for every x in the given function.

1) So, to find f(2), substitute 2 for every x in the given function, f(x) = x + 3x and solve:

Thus, for this function, f(2) = 8.

2) Do the same with the second question. Substitute -10 for every x in the given function, f(x) = 3x - 2.

Thus, for this function, f(-10) = -32.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

yes
