let g(x)=5x-2l and h(x)=x^2+1. Find the value of each expression. (h*g)(-1)
To find (h*g)(-1), we first need to compute h(-1) and g(-1):
h(-1) = (-1)^2 + 1 = 2
g(-1) = 5(-1) - 2 = -7
Now we can evaluate (h*g)(-1) by multiplying h(-1) and g(-1) together:
(h*g)(-1) = h(-1) * g(-1) = 2 * (-7) = -14
Therefore, (h*g)(-1) = -14.
To find the value of the expression (h * g)(-1), we need to first find the value of h(-1) and g(-1), then multiply them together.
First, let's find g(-1):
g(x) = 5x - 2l
To find g(-1), we substitute -1 for x:
g(-1) = 5(-1) - 2l
= -5 - 2l
Next, let's find h(-1):
h(x) = x^2 + 1
To find h(-1), we substitute -1 for x:
h(-1) = (-1)^2 + 1
= 1 + 1
= 2
Finally, we can find the value of (h * g)(-1) by multiplying h(-1) and g(-1):
(h * g)(-1) = h(-1) * g(-1)
= 2 * (-5 - 2l)
= -10 - 4l
Therefore, the value of the expression (h * g)(-1) is -10 - 4l.
