f(x) = x2 − 13 do you mean f(x) = x^2 − 13

if so then (x^2 − 13) + ( x + 5) x^2+x8 add like terms 3^2+38 plug in 3 where there are xs =4

can you help me with this one : Consider the functions f(x) = 13x2 and g(x) = 7x − 5. What is the value of (f − g)(3)?

I know this is alot but could you help me with this one to ? Consider the functions f(x) = 8x + 2 and g(x) = 5x − 3. What is the value of ( )(4)? Please show all of your work for full credit.

f[g(−4)] if this is right and you sure it is that then ooh you plug in the whole 5x 3 into 8x+2 in the x so 8*(5x 3)+2 40*x22 distribute the 8 into 5x and  3 then add the +2 Plug in  4 182

f(x) = 8x + 2 and g(x) = 5x − 3 (4) (8x+2) / (5x3) just divide then (8(4)+2)/(5(4)3) plug in the 4 where the xs are at 30/23
