Let f(x) = -2x +49 and g(x) = -4x + 3. Find
(fºg)(-5).

3 i think

Step-by-step explanation:

so we substitute -5 to g(x)

g(x) = -4(-5) + 3

= 20 + 3

= 23

now we substitute it to f(x)

f(x) = -2x + 49

= -2(23) + 49

= -46 + 49

= 3

3

Step-by-step explanation:

f(x) = -2x + 49

g(x) = -4x + 3

(fºg)(x) = f(g(x)) = -2(-4x + 3) + 49

(fºg)(x) = 8x - 6 + 49

(fºg)(x) = 8x + 43

(fºg)(-5) = 8(-5) + 43

(fºg)(-5) = 3
