Question

If f (x) = x+5, g(x) =2x-3, h(x) =2×2 +7 x, -15, i(x) =x+2 find h(4)​

Answer 1

Answer:

h(4)=17

Step-by-step explanation:

Since we are just looking for h(4), all the other equations can be ignored. Then we replace the x in the equation with 4. Remember to do the multiplication before adding the numbers together according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

$h(4)=2*2+7(4)-15\\h(4)=2*2+28-15\\h(4)=4+28-15\\h(4)= 32-15\\h(4)=17$
