Q. Given that f(x)=x−4,g(x)=4x and h(x)=3f(x)−g(x+3), then what is the value of h(5) ?Answer:
Find f(5): First, we need to find the value of f(5) using the function f(x)=x−4.f(5)=5−4f(5)=1
Calculate g(5+3): Next, we calculate the value of g(5+3) using the function g(x)=4x. We need to evaluate g at x+3, which in this case is 5+3.g(5+3)=g(8)g(8)=4×8g(8)=32
Use f(5) and g(8) to find h(5): Now, we use the values of f(5) and g(8) to find h(5) using the function h(x)=3f(x)−g(x+3). h(5)=3f(5)−g(8) h(5)=3×1−32 h(5)=3−32 g(8)0
