Question

If f(x) = x 2 + 1 and g(x) = 3x + 1, find 2f(1) + 3g(4).

Answer 1

We have,

F(1) = (1)^2 + 1

= 2

G(4) = 3*4 + 1

= 13

Again, we have,

= 2F(1) + 3G(4)

= 2*2 + 3*13

= 4 + 39

= 43

Answer 2

Answer:

Step-by-step explanation:

f(1) = 1^2 + 1 = 1 + 1 = 2

g(4) = 3(4) + 1 = 12 + 1 = 13

2f(1) + 3g(4) = 2×2 + 3×13 = 4 + 39 = 43.
