Question

f(x) = 3x - 13g(x) = 2x2 - 4x - 5h(x) = -4% - 76. Find (f - g)(x).7. Find (f - 5)(x).8. Find (f + 9)(x).

Answer 1

We would evaluate each expression.

For F,

13 + (16 - x) = 13 + 16 - x = 29 - x

(16 + x) + 13 = 16 + 13 + x = 29 + x

For G,

x + (4 * 5) = x + 20

(x + 4) * 5 = x * 5 + 4 * 5 = 5x + 20

For H,

7(10 + x) = 7 * 10 + 7 * x = 70 + 7x

(7 * 10) + x = 70 + x

For J,

(8 + x) + 9 = 8 + 9 + x = 17 + x

8 + (x + 9) = 8 + x + 9 = 8 + 9 + x = 17 + x

Thus, we can see that option J has equivalent expressions
